Onvif triggers creating multiple alerts version 5.8.8.8

[CamCrazy]

Hi, on my previous older 2022 install the onvif triggers would simply create one alert in Blue Iris, the new version on a couple of cameras seems to create 2-4 alerts for the same event. Sure this is something simple which changed, seems to be occurring with the RuleEngine/LineDetector/Crossed

Guessing this is due to higher sensitivity or similar with this newer version, maybe less extensive lines are required under IVS rules now?

Thanks
