I noticed that both Brave and Chromium browsers were updated (either two night ago or last night) and now I have two entries. One entry for the respective browser and what seems like the older one that I had moved into a folder. Please see attached image.
Did you create the folder yourself? Did you restart the session since the upgrade and if so does the issue persist?
I did create the folder myself, I did not restart the session. I just moved everything out of the folder which seemed to have fixed duplication. I should have tested it more and restarted the session. I will do so when the next Chromium update comes.
