Thank you @ rlithgow1 for pointing me in the right direction.
6 of the 10 ghosts won't delete using the built-in tools.
I found the Delete 2 Ghost Devices post and the How to Remove Ghosts Using Hub Tools or a USB Stick and am going through the process in the PDF document that was linked.
Of course, I have to do things the hard way...
Again, tip o' the hat to @rlithgow1 and I'll update once I get done removing all ghosts.
