T150 Glitches NFS Heat, Need Help!

Hello 

I am using the T150 on a ps4 and I found some glitches that either makes the game unplayable or it does not make sense using the steering wheel, which is the main reason why I bought this game.

1. When the shifter is connected the game does not recognize the steering wheel at all. Once you remove the shifter you can use the steering wheel. Why is that?

2. When driving the game has switched the clutch pedal and the gas pedal. So to drive you must push the clutch. If you push the gas pedal nothing happens. What am I missing? How can this be fixed?

3. There is no way to remap the controls when using the steering wheel. (If I could change the acceleration function from the clutch to the gas that would be amazing, but there are other controls I want to change also.)

Can someone please get back to me as soon as possible? I would like to enjoy the game.
