R7000 Sees hardwire device that is not on my network

I have 2 TV's in the house both of which I have the MAC addresses for. One TV appears on the Netgear Genie network map the other does not. There are two other devices that the genie sees and has labeled them as TV's. Neither of those are MAC addresses that I know of. One is listed as "wired" and the other "wireless" they are currently blocked. Both of my TV's can can access the internet with no issues, they are hard wired. Where did the two unknown "TV's/devices" come from and how can I eliminate them? I've already rebooted my router. TIA.
