I went to my “Sphere” BP" and click on my projectile and search for Expose. Nothing 
I then looked in My Character BP where I spawn the projectile by hitting space.
Looked at the Variable and the node “SpawnActor Skeet DM Blueprint”, nothing there either.
I did find it under “My Projectile REF” Variable in the “My Character Blueprint”, ticked it there. No change, still doing the same thing.
Am I just looking in the wrong place?
