waw acceidently put it in bo3

my power door leads to zone4 and it doesnt activate the zone4 spawners, i tried to put a trigger use "enter_zone4" on the power switch to see if that would work but it didnt.

im not sure why this is but i have a pathnode inside the window and there is traverse. occasionally 1 or 2 can get through but the rest linger in the back until they eventually die because they lived too long. Help me please, id be very grateful.
