Wrong target Android version shown (6.0 for level 22)

Example app: Clip Stack in the F-Droid Archive repo.

F-Droid shows that it's incompatible because it targets 6.0. That's suspicious in itself, as my phone runs an Android 14-based OS (crDroid 10.13), Android 14 only prevents the installation of apps targeting API level <23 according to sources like this and this, and API level 23corresponds to Android 6.0 according to sources like this and this (so an app targeting 6.0 should still be installable).

Then I looked at the APK in the App Manager app, and it said it targeted API level 22, which corresponds to Android 5.1. IzzyOnDroid also says it targets 5.1 (about the same package in the F-Droid Archive repo).

I don't know if there's any other API level for which the wrong Android version is displayed; it's worth checking. I also don't know if the bug is in the client, the server or in the packaging infrastructure, as I don't know where the conversion from API level to Android version is done; please move this issue to a different project if it's not in the client.

Note: I use F-Droid, not F-Droid Basic.
