Multiple PERSONAL.xlsb files - which to keep - how to delete

I don't know how this happened - but today, I was prompted with the following list of MULTIPLE personal.xlsb files
asked -- which one(s) to keep?

I opened each, checked out the MODULES and find that the very bottom (original PERSONAL.xlsb) file is a good one (has my most recent Modules in it)
Also, the very top one listed: PERSONAL (version1) - seems to mirror the original one -- with the same quantity of modules in my module list.

The other 2 listed in the middle did not hold all of my modules and should be deleted - but when I right click on them to delete; it's not an option.
See attached image -- to see what I'm seeing and to see what options are available when I right click (shown in red bordered window at right)
Is there a different place I need to go to remove those extra copies?

Hoping someone knows how to clean this up before something bad happens to my valuable Personal file!
Thanks!
