But when I perform a similiar query for a location in El Hierro island (also in the Canary Islands), it is also returning ADM2, which is redundant (with hierarchy=tourism parameter) because it is also returning the island (ISL):
Would it be possible for location hierarchy queries (with hierarchy=tourism parameter) in El Hierro island to ignore ADM2, as it rightly currently does for location queries in locations in the rest of the Canary Islands?
