Lighting needs rebuilt for streaming levels

Im making a game and I need to have levels be streamed. I put certain parts of the map in different levels and have a directional light and sky sphere in persistent. I make all levels invisible except one and persistent, then I build lighting, and do that for each level. Each level on its own does not show any build lighting errors, however if I unhide 2 maps at once all the sudden I need to build lighting.

This is one part of the level in a streamed level, it’s lighting has been built and is ok.

This is the second part of the level, again no lighting errors

Now when I make both visible, then i need to rebuild lighting

Is this normal? am I doing something wrong?
