Can’t change controller bindings in steam

I recently got the G2 and I just started Pavlov’s tutorial. In the tutorial it requires you to press the trigger and menu button to access the main menu but that doesn’t work on G2 controllers. I tried to edit the bindings to get it working and I activated a community made binding for G2 controllers in Pavlov, but now I can’t edit any bindings at all, and it says my bindings are set to default. Every time I try to click from default to custom it just doesn’t switch to custom.

Anyone have any solutions for this?
