Worlds wont open unless join and exit server.

I can't load my worlds on Xbox one unless i join and exit a server. For now its fine, but it would be nice if it could be fixed. If i don't join server, the world sits there, saying that its generating, but the box overlays the world menu. Then the box goes away, and i'm still on the world menu. If i try loading again, the box appears and then disappears, very quickly.
