Problem with url

When I translate a page of a property on this real estate website, the link of the property in Spanish works correctly, but in English part of the URL changes and then it does not open.
Right link: http://inmoandinvestment.com/web/es/propiedad/insigne-luxury-villa-no-6/

Wrong link: http://inmoandinvestment.com/web/en/property/insigne-luxury-villa-numero-6/

But when I change the web since the spanish versión, its ok.

The incident only happens when I open the link from home.

I need help. Thank you.
