My Question or Issue

Today (27 June) I've noticed a problem. Usually Repeat Rewind playlists is updated within three days (previously it was 5 days I guess) and I have noticed a lot of songs  I used to listen had disappeared. Only On Repeat had been updated, meanwhile Repeat Rewind remained the same and hasn't been updated like its above nephew. Is there a chance to get a further info about how does playlists work or fix that thing?

Thank you in advance for your statement.
