Incorrect number of used licenses

Just downloaded and installed Norton 360 that has 10 user licenses.  I have installed on 2 MacBook Pros, yet my account indicates 3 licenses used.  When I look at the devices, one of them appears to be listed twice, once as "My MacBook" and again as "my-macbook.local".  My other MacBook Pro is listed as "My MacBook Pro", with no reference to ".local".

How do I correct this?  I can see where I can delete a used license, but I do not know what that will do to the active subscription on "My MacBook".
