Settings don’t affect notifications

I was away from my home on a day leaves were blowing and setting off motion alerts for my floodlight camera. I first tried pausing alerts for all devices for 4 hours and the alerts didn’t stop. All devices were showing the icon that they were paused. Then I tried switching my cameras to detect faces only. This did nothing to slow down the alerts (I checked the video and there was not a parade of people going past the cameras). I turned off all the push notifications in the app, and the alerts kept coming. I ended up uninstalling the app for the day. Am I missing something?
