Logic Studio apps Patches won't change

Hi All..........I have a strange problem............I'm running Mainstage with a lot of controllers (10 so far) on a 2012 Macbook (8 gig) and I have a bunch of patches with different plugins etc and when I select another patch, the screen controls change but the controllers still play the first patch. It was doing this before the software update.I booted it up today and it worked ok for the first few minuets and then refused to change.
Has anyone else had this problem?
