Human only motion detection doesn't work

So, I’ve had the Eufycam 2 for a month now. I have it set up with two cameras.
Both cameras are set up for human only because I have been getting too many false recordings when it is windy and the trees/leaves are blowing.

Today, one of my camera stopped detecting human only detection. My wife took the dog out and I noticed that the camera didn’t record. When I switch to all motion, it works. When I switch back, it doesn’t work.
I did the motion test mode and the LED light does go on.
I also turned the camera off and on.

Why is this happening? Any way to fix this??
Thanks
