“Motion in a waypoint” doesn’t make sense. If “Track Motion” is enabled, the camera follows any movement in its field of view; it doesn’t matter whether it’s a waypoint or not.
You have “Pan Scan” enabled, which is why. Might want to try it disabled, see if that works in your case. If not, you have to live with it, because it seems to be overriding everything else.
Edit:
Ideally, once you press any of the pan control buttons, the camera should temporarily disable “Pan Scan”. This item has the potential to be added to the wishlist.
Even if Pan Scan is disabled, but if you have waypoint#1 set (the home position), the camera goes back to it, when the motion stops.
