VM OS upgrade - clients reporting back as clones

We upgraded the VM that Landscape is hosted on from 20.04 to 22.04.
This required landscape-server reinstall as well as postgresql version upgrade from 12 to 14.

Everything went more or lees smooth, but now I see that some of the client laptops are showing up as “Computers needing authorization” and they have (clone) next to their hostname.
We had a few clones showing up before as well, but never got any info as to what may be the cause of that.
Having to re-accept most of our laptops back now is a pain, so if anyone has any idea what might be the case here please let me know.
