Daily Mix Lists Not Populating

[cbjfan2009]

Operating Spotify via Apple device and Windows OS -- Why are my "Daily Mix" playlists not showing up?  I addded nearly 80 different groups when I signed up, I received 6 "Daily Mix" playlists, which were all quite excellent (props to the algorithm).  However, as I've started liking more songs on the multiple playlists (I switch back and forth every day to a new list, be it Daily 1, 2, 3, etc), the number of Daily Mix playlists has been cut to 2.  As I like more, I get less.

How can I "encourage" the algorithm to return my variety?
