Reply to BM Pro & Kontrol s4 using ver. 2.1.3 deck specific wont let me switch

Everything seems to work fine, but when i press shift and synch instead of switching focus on tracks it will just load a random sound from the maschine soundbank and do it for decks A and B. I am using a mac powerbook pro. I am just wondering if anyone else has had this problem.

In other words, the thing works great, but I just cant switch Focus. Any help would be MUCH appreciated.
