A340 - Reverse Throttle Calibration - Honeycomb Bravo - 2 Axis

[Spencer te Wildt]

I am having a really challenging time getting my reverse throttle to work properly with my honeycomb bravo.

I am able to successfully engage all reversers - but when I disengage - only throttles 1 and 4 regain power. See here: https://www.youtube.com/watch?v=Qz6Fj1FKvU8

I am using my bravo in a 2 axis configuration (having the 3rd axis control engines 1/2, and the 4th axis control engines 3/4). 

Interestingly, I have found that this behavior does not persist when I swap over to using 4 axes on my bravo (having 1 axis assigned to each engine).

I have tried:
https://www.youtube.com/watch?v=rvLUPkUhniE - This may not be applicable though, as it is treating the user as using 4 throttles
https://forum.inibuilds.com/topic/33760-how-to-calibrate-my-throttles/ - no change in performance between Toggle/Hold/Decrease

Any help would be greatly appreciated.
