how to spawn random number of actors in paper2d

i have created an actor blueprint for enemy character with his whole set of animations and health counters etc,.
i want to spawn a random number of actors of that enemy character blueprint when player overlaps a collision sphere.
based on my limited knowledge, i used an arrow component and collision sphere and when player overlaps the collision sphere i’m calling spawn actor from class in blueprint.
the enemy actor is created but it wont move. it stays on the spawned location.
