Invisible/deleted streams

A lot of songs I’ve listened to a lot don’t show my streams (or a very little part of them). When I click on the artist my total artist streams dont add up with a lot of the song streams. It seems as though my streams are still somehow saved, but not shown under the actual songs but only in the artist streams. When I look at my streaming history of that artist then all of my streamd appear but when I try to click on the songs where streams were deleted it bugs/doesnt bring me to the song (nothing happens when I press on the song).
