+1 on this, my CEM-25P acts even weirder. Whenever Ekos tells it to park, it cranks way past horizontal, in fact. I've had it crunch into itself -- maybe it's trying to go inverted? At any rate, I just don't use parking from Ekos.
Except that means that I always have to have the controller in my paw when I finish up with the Polar Alignment Assistant, because otherwise Ekos sends it haring off to Bog knows where. In fact since I moved to SM 1.5.2 on a Pi4 I have to slew the mount manually in the PAA, though otherwise GOTO seems just fine.
