Songs Not Able to Play Offline

[DonnyWon1]

For all of my songs, the first song, the first one for each letter will not play offline. It says that it has been saved and should be played offline but it just doesn't. Also, when I press on the first song of let's say songs that start with the letter A, it plays the song below it. How can I fix this issue because everything was fine for the first month of me using Spotify and now there are many bugs. Also, this only happens when my songs are ordered by title.
