FP2 Aqara best configuration

Hello world. I’m having minor issues with my FP2 Aqara me. I have two of them on 2 corners at 2.3 meters from the ground and slightly tilted pointing to a table and a couch. The issue I’m having is that when there are 2 people close together it tends to merge them into one, so when one of them leaves the room, the sensor stops detecting presence. I have the ai detection set off and all zones properly set and calibrated, even with stickers for forniture. Do you have any advice?

Thanks you all.
