LO detects Ctrl+V and Ctrl+Z twice

When I use short keys like Ctrl+V or Ctrl+Z LibreOffice (tried with Writer and Calc) does the action twice and it drives me crazy. Not sure if there’s some way to fix it.

I tried to emulate this behavior on other software like Kate (text editor) but it seems like the issue appears with LO only.

I use Manjaro (Linux 5.10.61-1-MANJARO with KDE Plasma); LibreOffice 7.2.0.4 20(Build:4)
