How to determine which of your devices are actively supported

So I have a 5 license Norton 360 account. If I log into the Norton website, under Device Security it shows 5 devices, and 1 more under History. My problem is based on the names of the systems shown, one of my systems has two licenses attached to it, one has a name I don't recognize and the system shown as Inactive in History is one that should be active (see screenshot). How do I figure out which license goes with which system ? Is there a way on the system I can see what Norton thinks the name of it is ?

Thanks

Norton 360 for Windows / Windows 10

What I am trying to figure out is how Norton differentiate between devices, basically how do I figure out which license goes with which system entry ? View Devices shows 6 entries, 2 have the same name, 1 name I don't recognize and the name in history I think should be active, so how do I know which is which. I figured it must be by MAC address or something, as it is the most unique identifier. I am trying not to have to start removing license and see what happens to figure this out.

Thanks
