Not sure but one reason why people keep renaming these roads is because Nominatim doesn't work well when whatever is in "addr:street" isn't in the "name" of a street nearby (not even when it's in name:left or name:right). If it's not actually the name of the street, then from what I've seen the best way to solve this is to change the address tag to something like "addr:place" or, in this case, "addr:terrace"
