V2 pan waypoint keeps changing

Waypoint keeps changing on my v2 pan cameras. Sometimes when I check them, the camera is pointing at an area that I don’t care about. Why? How? Is there a way to lock it in the desired waypoint? Also, if I zoom in on a part of the view, the camera will move and I don’t want it to do that. I often get very aggravated with these cameras as the playback is not what I wanted to see. That makes it useless.
