Mecanum Trouble

[REDBARON]

Our team is trying mecanum this year with four Talon SRXs and CAN, however we've been having troubles with the motors not behaving as expected, we are aware that the code from NI is not correct, but we've tried various configurations, and nothing has worked, we've ensured our SRXs are ID-ed properly yet still the code refuses to work, forward/backward, and rotate will work fine but strafing fail, or strafing and rotate work but forward/backward fail, all help is appreciated,
