why my maps keep the long LOC_XXX name no matter what?

[markto]

I tried creating a new map based on the YAMP map in the worldbuilder, edit the map name text tag to something, save.. but then when i try to start the game with it and then choose the map, in the map selection screen the map name is always that long LOC_XXXX name that came as the default.. i have edited the text tag to something else, and in the worldbuilder it shows that, yet on the game start selection screen it does not reflect that... why?

thanks
