Pitch Bend not recognized

Just bought Zeta+2 and for some reason it won't recognize my pitch bend on my keyboard controller.  I am running ProTools 12.4HD on OS X 10.10.5 on a new Mac Pro.  The pitch bend has always worked fine and still does on every other virtual instrument.  Just not Zeta+2.  I click on the 'Perform' tab and see the pitch bend info, it doesn't matter where I set it.  Doesn't work for me.
 
Any thoughts on what I am doing wrong?  Again, ALL other virtual instruments work (even in the same session) with no issues with recognizing pitch bend; just not Zeta+2
 
Thanks.

This is the first thread I recall about the AAX format of the plug-in. I am not sure how many users with a similar configuration visit this forum.
