My Question or Issue

For some (not all) of my playlists, there is no longer the "Shuffle Play" button, there is only a "Play" button. There isn't even an option to shuffle it in the menu options, there is only by which method i want to sort the songs. I just want it to shuffle! 

This was a sudden change that happened to my "Starred" playlist a month or so ago, and just now it's happened to another playlist. My "Favorite Songs" playlist still has the "Shuffle Play" button. What is going on here??
