**EDIT** To calibrate, try pressing and holding the shade button only (shut direction) first. Then try both as stated below if it didn't work.When closing it it stops short.

That happened to mine too. The shade has to re-learn it's start and stop positions.
I'm sorry, but I can't remember exactly what the procedure was, but I believe he opened the shade to end of the tilt glass. Then he pressed and held both sunroof and shade buttons (towards close) at the same time, for about 20 to 30 seconds. I think once the shade moves and stops that's when you let go.
