Power Save Mode activates automatically in GNOME

I run Bluefin GTS on my FrameWork 13 AMD Ryzen 5 7640U.
When i would like to change from PowerSaving Mode to Balanced, it reverts to PowerSave after about 8 second on its own, without any interaction from my side.
Is there maybe a setting which could cause the behaviour?
It is not a big deal because i like to extend battery by running in powersave most of the time.
