Distance Feature Issue

The distance shortcode seems to display incorrect distances. the listings display correctly on the map, and when I enter a postcode in the change location modal this works.

However the distance shortcode shows the wrong distance, when something is 5 miles away it says it is 3000 miles away in a different country.

Is this a bug or is something setup wrong?

All the listings are setup correctly with the map saving the correct position…

Also when clicking through for directions this is incorrect too.
