Maps in "My Maps" have no Map Source or ID

GaiaGps.com Windows 11

In "My Maps", there are 5 entries for the same Area. See screenshot of "My Maps" and 5 line items for San Bernardino Mountains. When I click on any of the Maps, only the area is shown. There is no information as to what map is being referenced.  How do I determine what map is referenced for each of the "My Maps entries"?

Thank you for any help.
