Custom controller mapping with wheel bugged

Using thrustmaster tx leather

When the leather edition preset is selected button A is assigned select and button B is assigned the back function… When assigning a custom profile (so Incan use buttons on the wheel unused by the default profile) there is no way to assign select and back functions to buttons A and B - no matter how you configure button mapping select is always bound to the triple line button and Back is always assigned to the double square button on the wheel. Super annoying.
