Here are my results:
Odd.
As I said, I assume you installed something that adds this functionality to gnome, but it is not a default in Ubuntu.

Not that I am aware of. Thanks anyhow. Is there any way to tell?
Thinking about it, check if you installed the âgnome-softwareâ app (which is similar to Ubuntus app center but deeper integrated with the desktop, so it might add such a feature to it)
OK, but check in which place? 
ETA:
Just checked the circle-dots one at the bottom, and nothing there.
Just checked the orange A with the halo, and nothing there either with that name.
Sorry.
No, there is a better way.
See Repositories/Ubuntu - Community Help Wiki for what is supported and what is not. Itâs changed little in 20 years and is well known to most folks. Not sure how you missed it.
AppCenter is a convenience that we recommend to new users for good reason â it protects you from folly. If AppCenter cannot do it, it might not be supported. When you find yourself looking for workarounds because AppCenter wonât do something, stop. You might be on the path to breaking stuff.

Thanks, but I did not even see any reference to the circle-dot thing âShow Appsâ, which has its own search and install/uninstall. Anyhow, what I was looking for is some sort of test/benchmark software I can run over the next couple weeks before the 25.10 update comes out.
Open App Centre > Type software in search box > Filter by Debian packages > Software (the GNOME project)
We appreciate that you are new, and learning much.
We do ask that --as part of that learning-- you acquire the habit of using names.
Others will find it much easier to understand what you are trying to communicate.
Open a terminal and with two quick checks we can see if additional functionality has been added:
dpkg -l | grep gnome-software
This will check if the package mentioned by @ogra is installed or not.
From your image, it appears you have flatpak installed, check with this command:
flatpak remotes
What search results you get when searching from the Overview is controlled in Settings > Search. Notice that Software is included in the apps to search. Thatâs referring to Gnome Software. Your search results in the âsoftwareâ area are just links to the applicationâs page in Gnome Software so that you can install it. Search is apparently not set up to search App Center (at least mine isnât).
If you switch Software to OFF, you wonât get any results from it.
So ii means installed ⊠since gnome-software is not part of the default install in Ubuntu (on purpose, since AppCenter fulfills the function already) you must have added it yourself at some point, like I said âŠ
Is that bad? Should I remove it, and if so, how? I thought Gnome was a part of Ubuntu, is it not? I could have sworn I saw in the new Ubuntu coming in a month, that Gnome software is a part of this, and not just a new thing, but an update.
Saw it here:
Nah, nothing is bad 
but you should keep in mind that your system simply is not default anymore and thus might behave differently to a normal Ubuntu ⊠i.e. the installation offering in the âShow Appsâ search page is simply not normal behavior, users that do not install a second software manager app like gnome-software (probably 95% of the typical Ubuntu user) will not see it âŠ

My bigger concern is that it will break in a month when the new update comes out. I donât really use a lot right now, honestly. Mostly Firefox, Brave, some graphics editor, LibreOffice, and Chirp. I installed a few things which looked interesting, such as âMiracle-wmâ, âPlasmaâ (maybe), âMesaâ (maybe), âKDEâ (maybe), âGnomeâ (thought until today this was part of Ubuntu), âflatpakâ, and that might be it. I can uninstall all of them, if that is what you are telling me will give best results.
Ubuntu uses parts of the GNOME desktop and also adds and removes things to/from it âŠ
For example the default GNOME does not support icons on the desktop, this is an addition Ubuntu does, GNOME also comes with a quite different panel layout by default, Ubuntu has the fully expanded launcher panel on the side instead ⊠Ubuntu uses its own software management tool (AppCenter) so the gnome-software packages are not installed by default and so on âŠ
Making a distribution is all about software selection and applying the glue to make the selected default bits work best with each other âŠ

Gnome Software gets installed when you follow the Flatpak setup directions on Flathub:
https://flathub.org/setup/Ubuntu
Step 2 installs the Flatpak plugin, which depends on Gnome Software.
BTW, For those who try to avoid Snap packages, Gnome Software is NOT a Snap package. Apt Center IS a Snap Package, and Ubuntu Software IS also a Snap package.
I wonder if I am mixing up âflatâ and âsnapâ. They sound very similar, even when reading them. 
In my experience, you always have to disable the software search in Settings; otherwise, it shows up even on a fresh vanilla Ubuntu installation,up until 24.04. I havenât seen those two rectangles in the top right corner, so maybe you installed something unusual that broke that functionality.
Edit: As stated by @ogra, GNOME Software is no longer included by default. I probably remembered it being present in older versions of Ubuntu. Thanks for the clarification!
