NOTE:

Every second time it is switched off, the wiper motor runs to an under-stroke parked position, that ensures that the lip of the wiper blade is flipped to the other direction.

To do this, windshield wiper motor runs down over end position and then back up a bit. This under-stroke parked position must not be used for aligning the windshield wiper lever.

You must use the position where the wiper motor runs directly to end position without under-stroke. Use "one-touch wiping" again if necessary.
