this is in labview
See attached drawing. Notice how the diagonally opposite wheels are always turning in the same direction as each other for forward, reverse, strafe left, and strafe right motion. But they go in opposite directions from one another for rotation.

Trace the wiring back from each front motor to make sure it isn't being controlled by the diagonally opposite rear wheel command.

Also, are you using home-brew code or the WPI Holonomic Drive vi? Cartesian or Polar?
