Paper2d Projectile won't collide Blueprint

Hi guys, i’m trying to make my projectile collide with another PaperSpriteActor in a 2D Game. The Actor can collide with my PaperCharacter but won’t get hit by the projectile. I’v tried several things like dragging the ProjectileMovment on top to become Root (selected component can’t be reorderd) or creating a Capsule around the PaperSprite without any luck.

Anyone has an idea what i’m doing wrong here ? Thanks in advance!
