No, you are not supposed to manually adjust the sensors to zero. That's what the ahc system is supposed to do for you. The main function is that it pumps up the pressure until the sensors read zero. That your system stops before it reaches zero is strange indeed.
Is this a typical reading for every time you move from Lo to Norm height? Do you let it go all the way down to Lo, let it settle, and then let it go all the way to Norm, wait 30 sec and then check the reading? Do you ever see zero on the height reading?
Flaky signal from height sensors can give harsh ride or varying heights. The sensors give the ECU input about the road condition in addition to the actual height, which is used particularly for wash-board control, e.g.
