Not showing right currency

Hi, my site is emprendemy.com

Currency used to show ok to different users in different countries. But now, it is not working anymore.

Autodetect currency is on, and Geo API is set on woocommerce.

And just to check if WC geolocation is ok, I tested it with a php script and it is working perfect.

Cache plugins are turned off just to ensure the problem is not there.

So I need please some help to show those currencies ok.

Thanks
