Skid steering setup problems

Building a drone boat with two fixed T200 bluerobotics thrusters. Wanted to set up skid steering using two paddles to control each motor individually. All attempts to do this has failed even after trying all setups recommended for ardurover. Currently have boat setup so left stick(throttle) controls both motors and right stick controls steering (proportionally increase/ decreases motors) Also in RTL and Auto the boat moves side to side the goes in opposite direction, checked and all orientations and setups for the here3 and orange cube seem to be correct

Have you checked the motor direction and Motor Driver Types setup?
