Unwanted VR_Gun floating in game

In the First Person Example level.
I make a new (empty) map.
I make a copy of the First Person Blueprint and add it to the level.
In play, a copy of the VR gun is floating in the level.

I make sure it’s set as hidden in blueprint, it’s still show up.

I delete all references to it in the blueprint.
Still there, floating.

I delete the mesh.
Still there, floating.

Where is this coming from, and how do I get rid of it?
