CamV2 Detection Zone bugging out once in a while

I’ve been using Wyze Cam V2 for years, I have CamPLUS. Usually detection is pretty good with my sensitivity around 75.

BUT every once in a while my detection just goes crazy and the zone gets completely ignored like today. I put my sensitivity to 1 and I still get notifications for nothing every few minutes. I tried to reset the cam, and reset the zone, but no difference. Any suggestions ??

Here is a few screen shots.

Is it going from sunny to overcast? The detection zone detects a change, not necessarily movement. So shadows disappearing and reappearing, etc can set it off.
