Missing tracks in large playlists when changing sort to "newly added"

[qberty]

Hey!

Got a new android phone and i ran into a weird bug that if i change the sorting order in a big playlist to "newly added", alot of songs goes missing and the order is completely off! 

I have made a screen recording so u better understand, the app language is in swedish tho.
