My mgm224/18 controller is behaving strangely lately!!!

Hey, it turned out that I already have upgraded(3.23) MGM. And I figured what is causing problem. When my car is on slanted surface and ran backwards because of the gravity I applied brakes to stop it from rolling reverse direction. and all of a sudden it ran backwards.
I guess reverse rotating is causing some confusion in controller causing it to go in reverse directino. Well... I guess I will just not apply break if the car rolls backwards.
