Starz on Hulu using X1 Hulu app

Added STARZ to my Hulu subscription and it does not appear as an add on when I use the new X1 Hulu app on my TV. I have a Samsung Smart TV and when I access Hulu from the smart tv app the add-ons are there.  Don't really use the smart tv features and would definitely prefer access through the new Hulu app. Has anyone had this problem and found a fix? Thanks in advance!
