Event OnHit(ObjectReference akAggressor, Form akSource, Projectile akProjectile, bool abPowerAttack, bool abSneakAttack, \ bool abBashAttack, bool abHitBlocked)

When I place this event on a NPC and shoot them with an arrow. It returns !projectile???????

The aksource is the bow but the event will not register an arrow projectile as a projectile?????

Is this correct???? And is there a work around?????
