Self made level not bieng exported

I added a level to the shooter game the comes with unreal. When I export the game I make this level “Industrial Space” the level in packaging-list of levels to include in packaging. In maps and mode I make this the map in editor startup map and Game default map. When I export the game the only levels that show up are “High-rise” and “Sanctuary” the two levels that come with shooter game. How can I get it to export the “Industrial Area” map as well?
