Hello @abc-mikey, this is expected and normal for the "Installed" section. Proton is considered a tool instead of a game, and it's useful to have access to some of the options in Manage Tool.
This is unexpected enough behaviour that I couldn't distinguish it from a bug.
As a suggestion maybe disable the pay button to at least prevent the user getting an error.
