Offline Playlists Keep Getting Removed

[Tallah]

Hi all, I've been using Spotify Premium for a couple of years now.  Lately it seems like my offline playlists keep getting removed. This seems to have no rhyme or reason. I have to redownload them at random times. Not all of them are gone, either.  I usually like to have five or six playlists and then I'll want to listen only to find out four of them are gone, leaving just one or two available.  I don't understand why this happens or how to fix it. 

Thanks in advance.

Usually a clean install is the first step to take and resolves most of the usual issues; the guide details the steps to take to ensure a full 'clean installation' is achieved - This includes checking redundant folders, removing offline devices and a REBOOT!
