Why Projectile does not collide with enemy pawn

On your first image, you have it set to “Query only, no physical collisions”. This means it will only respond to collision events. But won’t physically bounce off it. If you want it to bounce using physics when hit, then you need to set it collision enabled, or physics only.

I have a Projectile , but it is not colliding with my enemy character
Any ideias?
