Stealth kill addon - trigger acting as a collider

[formatc2013]

Hi guys can anyone help me with the Stealth kill addon?

The trigger under the ai parent gameobjects(passive one) is a box collider with the istrigger on, but it acts as a collider. (Is it intentional?)  I tried to set the layer on it but it is reset when i hit play and i am not really about to mess around with layers anyway.
I would like this to be walkable just like any trigger.

Thanks

It's not working in the demo scene included? I'm not aware of any going on bug in the Stealth Add-on, can you record a video showing the issue please?
