The map is in a very early stage and has some bugs that need to be fixed. For example if you try to send the map to a Garmin device from TopoNavigator you won't be able to see all off road categories because the app won't sent along with all the other map elements the TYP file.

As you can see the screenshots are from the same area of the map and it sure looks like there are two different maps although it's the same one.

The magic word here is patience ...
