Some songs are not displayed as liked (empty heart) in the Artist overview page, while they were liked, are present in "Liked Songs" playlist and are sometimes displayed as liked (filled heart) when looking at the album, but sometimes - not. Feels like some albums have multiple copies in the database.
Hey @nishbo, thanks for your post! Yes, Spotify sometimes has multiple versions of an album in its database, and I've noticed similar issues to what you've described on occasion. I would guess it's often tied to re-issues and that sort of thing from the studios. Unfortunately, I'm not aware of a workaround to make the liked songs match to different versions of the same album that are hosted on Spotify. The best way to fix it would just be to re-save the version that's displayed on the artist's page, and then remove the version you currently have saved; of course, if you've added the other version to any of your playlists, the heart indicator would then be removed from those.
All that said, you might like to submit this as an idea here.
