Phantom outlets in SmartThings

I’m using SmartThings with my Samsung refrigerator and my Ohmconnect plugs and the interface is working fine. I recently noticed two new Outlets in my home that didn’t exist before. “outlet1” and “outlet39”. The first I can turn off and on, but have yet to discover what is turned off or on. The latter appears to be permanently off.

I assume these outlets are connected to my home wifi, but have no memory of connecting them and can’t imagine what/where they are. Has anyone experienced this before?
