Thanks for the bug report. I'm not able to reproduce this on Plasma 6.6.3 or built from git-master. Can you please attach your System Monitor config file, which is here: ~/.config/systemmonitorrc Thanks!

Created attachment 191504 [details] system monitor config file Hi, here the file you requested but I think it doesn't contain anything useful. Also I updated to version 6.6.4 and the problem still exists.
Created attachment 191505 [details] applications.page with duplicated columns Hi again, I found something while looking around. The file "applications.page" in ~/.local/share/plasma-systemmonitor has the problem: every time I change the column type, the name of the column is appended to "sortedColumns" If I remove the duplicated column and restart the application the problem is gone. I haven't specified it before but my locale is it_IT.UTF-8, may be it's something related to it... I have attached my applications.page file after changing memory column two times.
Thanks for the added details, those are helpful. I see what you're talking about in ~/.local/share/plasma-systemmonitor. The System Monitor maintainers will have to take a closer look.
