Reverse geocode: City same as country in response?

I'm using the HERE Maps reverse geocode API in, and a user from Pakistan sent a report that both the country and city are being reported as "Pakistan" for the co-ordinate pair 31.522473692893982, 74.33312326669693. I have double-checked and found the same error; this is the response:

{"items":[{"title":"Pakistan, Pakistan","id":"here:cm:namedplace:22928320","resultType":"locality","localityType":"city","address":{"label":"Pakistan, Pakistan","countryCode":"PAK","countryName":"Pakistan","city":"Pakistan"},"position":{"lat":33.70964,"lng":73.07545},"distance":0,"mapView":{"west":60.87305,"south":23.7033,"east":77.13585,"north":37.07742}}]}

Both countryName and city are reported as "Pakistan" – this is incorrect factually and confusing to the user. This is also hard to deal with programmatically in my app – city should be blank if it doesn't exist and I can code a check for that.

The above is a co-ordinate from Lahore, the 18th largest city in the world! I get this same error when using the co-ordinate pair 31.5204, 74.3587 – which Google reports as the center of Lahore. There is no excuse for HERE not to get this major city right at least, even at a locality level.

Thank you,

Naved

For Pakistan, HERE Reverse Geocoder V7 API currently only has access to the Entry Map, which is a content place holder rather a valuable map. It is planned to increase the map coverage in Pakistan by 2020.

This can be indeed confusing. Try the Places API instead. For the coordinates you used, it returns Lahore.

GET https://places.ls.hereapi.com/places/v1/discover/search?
  at=31.522473692893982,74.33312326669693&
  q=31.522473692893982,74.33312326669693&
  apikey={{apiKey}}
