I inherited a spreadsheet, and in the names table there are a bunch of unrecognizable names; for example:
DomainEntity9d7895027c2048eeac0ddc9264f219d4

They have Workbook scope, and refer to something like:
=Sheet2!$B$2:$B$12

But there is no "Sheet2" tab defined in this workbook.
They do show a value, but a search for some of the values fails (i.e. they are not in this workbook), and trying a GoTo does nothing.

The Values look like this:
{"1 {Active}";"2{Inactive}"}
Like some sort of system mapping table - but again, the words in the map are generally not even in this workbook.
