if your polar alignment is out you will get a lot of field rotation when pointing close to the celestial pole, when you are pointing to the east or west the drift will be present if the altitude is out of alignment and when you are imaging near the meridian drift will happen if the azimuth is out.
the L shapes should happen across the field, maybe it didnt show up very well on stars that were not so bright ?
if you dial in your polar alignment it should sort these issues out.
