Kaya Sim cannot rotate vehicle with Joystick app

Omniverse Isaac Sim
1

I was trying the joystick app in Isaac Sim Unreal Engine Environment. I changed the move_axes to 0 and rotate_axes to 2 because the default settings could not work, ie the Kaya could only turn when pressing manual mode button but could neither translate nor rotate. After I changed the axes settings, I could move the Kaya with the left stick but not rotate the Kaya with the right stick. Please advise.
