I have to manually set Proton version for every single Steam game

I just installed Bazzite on my Legion Go S, and it’s incredible, except one hideously annoying problem: Even though my global Compatibility setting is specifying Proton 10.0-4, no games will launch unless I manually specify a Proton version in that game’s individual settings. The global Proton setting is being completely ignored.

Any suggestions on fixing this?
