Creating a new level in the content browser does not give user the choice of a default or empty level.
1. Open Editor (any project)
2. In Content Browser, RMB in empty space near assets>Level
Level is created, no prompt is given to choose default/empty
Level is created, prompt appears asking user if the level is default or empty.
