Actor always shows same face

Maybe my pictures are not good enough to explain my problem… next picture shows three views from the same 3D objects as it should work, previews images shows what I get now.

Moment 1 and 2, works perfect. Moment 3, when I want to see the opposed side of the “cube” is the problem. In my current work, does not matter how much I turn around the actors I ended with the layer 1 always on top.

Thanks for your help.
