Yes it’s pretty strange, I have a couple of the older models that pan and tilt and they’ve never done this so hopefully just a software issue that can be resolved soon. I have mine storing to the SD card so the home base must not be the issue. Not sure if yours does the same, but the movement on mine isn’t near as smooth as the calibration or panning motion and vibrates while it’s doing the random turning. That’s how I figured out it was doing it since it vibrated itself off the edge of a shelf
