In multiplayer projectile always deals 10 damage

Hi! I’m new to creating online games and I’m trying to make a co-op shooter with a top view. I’m running into the problem that projectile always does 10 damage to the ai enemy, no matter what I set in Apply Damage. Why is that so? And what possibly can fix it?
