Unable to localize wikiloc information

Problem/Motivation

I don't know if this is a bug or if I am missing something. The code includes the automatic localization of the map, but I cannot make it work.

With the following map (created in Spanish): https://es.wikiloc.com/rutas-senderismo/sendero-acequias-de-paulo-y-el-c... the information displayed is in English, with feet and mile, independently from the browser or Drupal local configuration.

On the module page, the screenshot is in Spanish, so I presume it should work, so maybe I am missing something, but apparently there is no additional configuration available front-end.

Any suggestion?
