Albums are not displaying on Album categories

What happens?

Albums created on our instance are not showed on "Album" categories (Explore > Albums and My library > Albums).
In contrast, libraries (third party content) are displayed on those categories.

Context

Funkwhale version(s) affected: Version 1.0.1+git.68bc76bc Instance: https://audio.anartist.org

We are the maintainers of the instance, so we could access more info if needed. I think this is a quite important problem.
