Detection Zone fault

The detection zone setting on my V3 doesn’t work on either of the two cameras I have at the front of my house. We have a flag in front of our house that triggers the cameras continually, the cameras also frequently tag the flag as a person or vehicle but thats another issue.
I set up a detection zone so not to detect flag movement but it still does.
Any ideas how to rectify this?

Able to post photos of your detection zone and an event video with the event tagging enabled?

I’ll try to post one

If the flag is excluded per the detection zone, is there anything else in frame that is being detected as motion? Any color changes or lighting changes? Shadows? Enabling motion tagging and then getting event videos after that should tell us.
