Āzādshahr, Iran: Does this city actually exist or is it misplaced?

Āzādshahr, Iran is given as a city with over 500k pop and located at almost exactly the same place as Hamedan, but I can't seem to find it anywhere on a map. There is a city by this name in the Golestan province in northeastern Iran, but with fewer than 50k inhabitants. Was this a mistake in the data source?
