I finally found the problem, just don’t know WHY, but when my right most toggle switch is engaged on the Bravo then the Avionics 1 switch on the Alpha will work. I’ve unmapped and remapped the bindings and it hasn’t helped, but at least I can use Avionics 1 again on the yoke, just had to sacrifice that toggle on the throttle, luckily it has so many I’m good for now. Hope that helps you!
