Without probing the values while running, I can only guess at a cause.
One possibility is that when the joystick is pressed forward along the Y axis, there may be some slight X axis value other than 0 being fed to the Holonomic Drive block. This might cause what you are seeing.

"Run" the program from LV and probe both the multiplied Y and multiplied X lines feeding the Holonomic Drive block. It will give you a real feel for what is happening. If the result you see doesn't explain the issue, you will need to dig deeper.
