World Composition not working after Join Server?

Hi everyone.
I make a world composition level, and with some sub level.
When I run the level in editor it works fine.
Then I run a listen server hosting this level (as game scene):
[UE4Editor.exe BigworldMoving.uproject ThirdPersonExampleMap?listen -server -PORT=27777 -log]

And I launch a client on different level (like login scene, lobby scene). And I use cmd
[open 127.0.0.1:27777]

Client will connect to the game server and change scene, Character and the Actor in Persistence Level can create in the client. BUT the level streaming not working at all. the sub level don’t load at all.

How can I solve this problem?
Thanks for your answer.

here is the join session blue print i used

and level stream is not work
