It should be noted that the discography feature never showed you library albums explicitly. It always showed our version of the world, and if you lack music from outside your library (meaning no streaming), we actually just hide that tab completely.
The “albums in your library” section at the top of the first tab in the artist details is meant to be the ‘your stuff view’.
We are having discussions on how to improve this to include “duplicates” and “versions”, but that is outside the scope of a “hot fix” like the one we just released.
