I actually sell these. You can manually lower the door to the height that works comfortably, then hold the automatic door button down for about 3 seconds. That should program the door to a new maximum height.

How do I set the height on my vehicle’s adjustable power liftgate?

When the liftgate reaches the desired height, push the rear liftgate close-button once (button is located on the doorjamb of the rear liftgate, and only accessible when the liftgate is open). Press and hold the button until it beeps 4 times. Click here to view a video.
