Please help me, my G27 wheel is acting up.

So i bought the wheel about 2 hours ago. I contected it to my pc and all. For some reason, in game it auto accelerates and it auto switches gears. I have it on pro settings to see if that would help, i cant seem to use the shifter or the clutch. When it was on pro i was able to use the paddle shifters but it would still shift on its own if i didn't do anything and it would still accelerate on its own.

Any ideas?

Ps: i already did download the drivers from logitech.com/support/g27
