System monitor column headers not showing

I’m running a fresh install of Fedora 44 KDE.

KDE Plasma Version: 6.6.5

KDE Frameworks Version: 6.26.0

Qt Version: 6.11.1

When looking at the system monitor, the column headings are missing for CPU, Memory, and some others.

When I start system monitor from the terminal, I see the following output, it prints out continuously while running the program:

qrc:/qt/qml/org/kde/desktop/HorizontalHeaderView.qml:38:9: Unable to assign [undefined] to QString

Anyone have any ideas on how to fix this?

Right click column header > Configure…

Note that this app is buggy. Do one column at a time then click away to Overview then back again to set another, or you may need to do one and then restart it.

(I found this thread because I’m looking for other reports of how buggy it is!)
