One of my playlists disappear when I go into offline mode

[Anethar]

I have a Galaxy S2. Recently, when I started going into offline mode on my cellphone (yes, I have Premium), one of my downloaded playlists started disappearing. The playlist title is there, greyed out, but there are no songs in it. However, when I go into online mode again, the songs are all back. I de-synced all of my devices and reinstalled the app but no change so far. Any ideas on a fix?

Sorry if it has been asked before. I looked for a similar question, but most posts complain about ALL of their playlists disappearing

That sounds really weird. What's the name of the playlist that's being difficult?
