How to Push IA NPCs Enemies back with blueprints on UE4

Hello, I would like to push all the enemy IAs that are following me (with a simple move to location node).

The problem is that when I push them with my “weapon” (a cylinder) I can only push three of them, when their are 4 or more I can´t push/walk to them, they block me.

I would like to know how can I modify the “enemy” BP to allow my main character push them while their are many at the same time.
