Thrustmaster TH8A shifter has no reverse in GT6

[Blown Camaro]

I am using a G920 wheel & pedals and a Thrustmaster TH8A shifter connected to a Drive Hub. Everything works perfectly EXCEPT I have no reverse. It's really weird how that's locked out. Triangle is supposed to be reverse but does nothing. E-brake is circle and works as it should. Shifter works perfectly fine except no reverse there either. I am baffled. I even tried reassigning reverse to down on the d-pad and now that does nothing (it was look behind before).

Any ideas on how to get reverse working on either the shifter or the wheel?
