Projectile Collision Missing In FPS_Character

I’m Having An Issue With The Unreal’s

First Person Character Collision Is Missing The Projectile Collision Under It’s Collision Settings

I Have No Idea How It Disappeared But Would Greatly Appreciate It To Receive Feedback About This

Try this:
Go to project settings - collisions. Delete Projectile Object Channel. Make new Projectile Object Channel.

Thank You Very Much,
Your Help Will Be Greatly Appreciated
