C5L - Sensitivity problem

I have issue with sentitivity on my C5L.

since the update of the firmware i made a couple days ago, even if i put the sentibility to low/none to high, i have a notification for every single movement.

Does any change have been made with the sensibility tool ? its pretty anoying to have notification when someone pass in the street. (we just see foots and i got notification)

Thanks
