How to make enemies choose a free path

The ai players in grey all pile up to one door when the other is wide open. How would I go about causing the enemies not close to the green player look for an open door, and more advanced if possible, begin a scripted event like “climbing through a window.”

more info: I’m using RVOI avoidance. tried crowd controller. I don’t know exactly what each setting does. I can’t find a tutorial for this exact scenario. Help? please and thank you!
