My Question or Issue

There are some songs that will show up as saved on the library, but when playing them the app shows them as not saved. See the screenshots attached.

First, the library shows 'Take What You Want' by Post Malone as saved, but the player doesn't. (The heart is filled on the library indicating that you saved the song, but the player will show the empty heart, like you didn't save the song)

Second, the player shows 'You Know You Like It' by DJ Snake shows up as saved (you can see the song in the library when I searched for it), but the player shows it as not saved (empty heart)

This happens on every platform, but doesn't occur with every songs. It mostly happens in a per-album basis.
