Created attachment 131139 [details] After choosing incompatible option
Created attachment 131140 [details] Options to choose from (48 and 120 are from another laptop the data was copied from)
Another information: due to kpartition manager erasing my home partition I had to start with a fresh profile, turns out the issue still persists ? Also exists in version 5.19.4 (Fedora 33 Beta).

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Plasma 5.25 or 5.26? If it is, please change the status to CONFIRMED when replying. If not, or if you can't because you no longer use this setup, you can change the status to RESOLVED WORKSFORME. Thanks a lot! What exactly did you copy, can I ask? I suspect that was not relevant.
I'll mark it as FIXED as I can't currently reproduce the issue due to not having the hardware anymore.
