1.16-alpha - Apps unique to other repos sorted above f-droid.org are not listed

• Device OS and version: divestos 20 (android 13)
• Device model/manufacturer: OnePlus 7T
• F-Droid version (in the About screen): 1.16-alpha0 and 1.16-alpha1
• F-Droid privileged extension version (if installed):

What did you do? (clear steps if possible)

I added the IzzyOnDroid repository: https://apt.izzysoft.de/fdroid/repo

What did you expect to see?

I expect to see the apps from the IzzyOnDroid repository listed in the f-droid client

What did you see instead?

I have noticed that with the alpha 1.16 versions (both alpha0 and alpha1) of f-droid, apps from the IzzyOnDroid repo are not visible:

if an app is present both in the official repo and in izzyondroid it is visible from the client and you can decide which version to install (an example is fairemail, I can see both the version of the official repo and that of izzyondroid), however if the app is only present in the izzyondroid repo it is not visible, for example if I search for aves I only see aves libre (the version of the official repo) and not the aves version of izzyondroid.

The problem seems to occur only with the izzyondroid repo (at least among the external repos I use) and no errors are reported when updating the repos.
