Person Alert at Night After Car Identified

I hope you can help with with person alerts at night. BI/Deepstack identify a car on the street pull up and stop in front of the house. This alert is noted just fine in BI. A family member then gets out of the car and walks to the house. The person alert is never noted in BI and there is no dat file. When I review the recording using “analyze with AI”, it shows a person with a confidence level over the minimum value. This is a very common problem for me. Any ideas? Maybe I have a value set too high for the amount of time required between alerts? Currently, I have all timers disabled.
