The location data are set by the Mapquest itself and when we tested the WP Travel Here Map in our side, regarding the location, it is working perfect.
Actually, WP Travel Mapquest and WP Travel Here Map are powered by the Mapquest and Here Map respectively and the data of the location are given by their respective server. Functionality wise, WP Travel Here Map is working perfectly fine.
Hope this clears your confusion.
