The distances are relative to a blue marker on the map, which you can drag to your current location. For me, it was in the UK and completely hidden by one of the boxes. I just happened to notice it during the refresh after manipulating the map.

Namely:

  .overlay-label {
    border-radius: 5px;
  }

lol you guys seriously hate hard corners, i don't think there is anything wrong with it.

hmnn indeed looks better. Updated. Thanks.

kilometers too pls :)

yeah it's pretty useless, I'll change it to district and country where the place belongs to.
