I had something a little similar happen when I listed my Airbnb apartment on Google Maps.

In their infinite wisdom, Maps decided it'd be best to merge my listing with the listing for the building it's in - but also gave me admin rights over the entire building's listing.

Support refused to fathom that I don't want to have any degree of Maps authority over something that does not belong to me (though I could have definitely used this to my advantage for increasing bookings), and their instructions to unsplit/remove myself never worked.
