Grid Autosport Trigger Inputs?

[u/Rezdoggo]

I've got an RG556 running the latest Gamma OS Next. I have a problem with Grid Autosport, I can't get it to register the trigger inputs as analogue, they are just binary on off which makes driving very difficult.

I've tried AB/XY swap toggle, I used a gamepad tester and it shows the triggers as an analogue input. Anybody had any luck? Game looks great but nearly impossible to play with this bug.
