shifting gears suddenly changes from my shifters to buttons on my wheel?

as the title suggests i have this problem where my shifters on my G920 wheel suddenly wont change the gears, but instead the X and B buttons on the wheel?

I have no idea what causes this, it seems to happens regardless if my normal xbox (elite) controller is on or off.

any ideas or fixes? im on Xbox One X

PS: get the new collisons and penalty system in ASAP online is a total disaster !
