App Lounge installs BETA releases of some apps

I have already noticed a few times that the App Lounge also installs BETA releases of some apps. I had noticed this the other day with Proton Mail, but now also with Proton Drive (see screenshot).

Have any other people noticed this? I think it would be better if App Lounge only installed stable releases.

there’s a backlog issue for the behaviour where the source is F-Droid. Might create a new one for when the source is the Play Store attached to this -
