Ok did you change the offsets in the boxes at the site? it moves the whole map in that direction.
1 open the .map file of the map
2 check some z coordinates (the altitude in meters i think)
3 if they are 10000.112312 then they are 10000 meters over sea. The offset should be about -9900 in z to get it down to about 100m over sea.
I havent tried, but i think it is this way
