Remove orphaned preview asset

I removed my grip socket with a preview asset attached. When I did the preview asset dropped to the ground. Now I can’t remove it and it shows in my game. Is there any way to remove this without starting over? The Remove Attached Assets option doesn’t work. After reloading the animations the rifle disappeared but it’s still at my feet when I play the game. I tried closing the editor and reloading but that didn’t help either. Now the only place I see it is when I play the game.
