Trouble with Function Keys

Hey there,

I'm pretty new to Manjaro and I just installed it on my Convertible and my PC. I'm using the KDE Edition and I'm having some issues with my keyboard. My Keyboard has an FN-Key, and Brightness Up and Down Keys. When I go to Setting>Shortcuts, the Brightness Keys are set to Brightness Down for Brightness Down and Brightness Up for Brightness up.

The Problem now seems to be that Manjaro treats all 3 Keys the same, recognizes them as Brightness Down. When I press FN, it toggles between F1/F2 and Brightness Control but also decreases Brightness. When I press Brightness Up, it also turns Brightness Down instead of increasing it.

Do you have any suggestions on how to deal with this problem? I could not find anything helpful while researching.
