Streaming levels

Hi. I’m creating streaming levels for my game and now I’m facing a problem.
This is how my persistent level looks like.

Persistent Level

  • Cover
  • Loading
  • Game
    • Room1
    • Room2
    • Room3

I’m going from Cover to Loading and from there to Game. Inside Game level I want to Load the next level Room1, but it’s not working. Why is that? Because if I load the map Game and I play it all the rooms are loading fine. Is this because are not inside the root Persistent Level?
Thank you!
