Can't trigger instruments in Bank 2 with external MIDI controller - it stays on pattern. Bug?

I am using Groove Agent 5 Stand Alone but this problem may exist from within Cubase. I have all 8 banks set up on my Maschine Mk3. I can clearly see Grove Agent responding to all 8 banks x 16 pads. If I switch from pattern to instrument then sure enough I play instruments from the M3 instead of patterns - except in the case of Bank 2. That plays patterns regardless of the pattern/instrument selection. In the stand alone app itself it works fine just not from the controller. The controller is doing what it should. Any ideas?

OK you have to switch “turn all pattern players off” left of Undo and it works.
