How to add different levels to the package?

I have a default Menu map in my game in which selecting the appropriate level is handled by using Open Level node in the blueprint. When I package the game as is, it crashes whenever I select to play the tutorial or the main game which led me to believe that the levels aren’t packaged appropriately - so I added this to the DefaultEditor.ini:

    [AllMaps]
    +Map=/Game/TopDown/Maps/dsflg
    +Map=/Game/TopDown/Maps/tutorial

Now it doesn’t crash anymore but it just blinks and goes back to the menu when I choose the main game (the former level) or the tutorial (the latter). What can I do to package it so that it works right, just like in the editor?
