Why am I not able to calibrate/use the Spoiler arm and the Reversers when I use my Precision Flight Control , 2 or 3 or 4 engine jet Spoilers/Throttles/Reversers, throttle Quadrant in X-Plane 11. I pick the 2 or 3 or 4 jet in the special equipment option in the Joystick setup. I am able to calibrate the engine throttles but I cannot calibrate or use the Spoiler arm or the reversers.
