Problem syncing some play list for offline listening

[mwilson96]

Having a problem for some of the new play list that a make available for offline. For example if I make a play list available for offline at night the next morning it will be gone and I will have to do it again. And it will stay for about four to five hour then it will be gone. But if I download a old play list for the most part this well stay. Not sure what the problem is if anyone can help that would be great. Thanks for your time.
