I used to be able to move tracks up and down in a playlist I have made without issue. Now all of a sudden I am unable to. When I try to move selected tracks higher or lower I am shown a prohibition icon (circle with line through it). It doesn't matter if I attempt to move one or more tracks, they still won't move. 

I don't have any of Title/Artist/Album/Date parameters selected, which is the solution given in other threads of this nature.

I am still able to move tracks up and down in other playlists that I have made. I am able to move tracks into the problematic playlist, they end up at the bottom of the playlist as per usual. I am also able to move tracks from the playlist into other playlists. 

I have closed and re-opened the program multiple times. 

Any ideas?
