The attached chart shows the situation if OP meant to say that a rotate clockwise command
caused the front wheels to rotate forward and the back wheels to rotate backward.

• Green means wheel rotation forward
• Red means wheel rotation backward
• Columns B D F H J L show what it should be
• Columns labeled "?" show what it is actually doing (per OP's testing)

As you can see, swapping the FrontRight and BackLeft motor commands will correct the problem:

• the RCW and RCC will be corrected, and
• the already correct FWD, REV, STR, & STL will be unaffected
