Distances on the Map are a little out. please recalibrate

In the list on the left i can see three posts

On the map i can only see one. The other two are about 100km further out and the list should only be showing me what’s currently visible to me on the map.

Please recalibrate this.

There is a related task, that users should open the map zoomed out to a distance where they can see a minimum of 5 posts on the map, if more than that aren’t visible in the default zoom scale. So no-one ever sees an empty map. You might want to complete these two at the same time as the code will be largely in the same place.
