Drive Train Curves Only While Backing Up

We're using a 6-wheel drive train (3 on each side) with a mini toughbox. Our motors are 4 KoP CIM motors and we're using 4 talons for our motor controllers. We're splitting the PWM cable so we're only using two PWM cables to access the 4 talons. We're kind of unsure what this could be so I was wondering if anyone had an issue like this before or what your ideas might be as to what's causing it.

Thanks!

Are you making sure to set all of the talons manually? What do the diagnostic lights on the talons do when the robot is backing up?
