Visual Composer Duplicating

Hi, i’m having the same problem.
When i try to add content in frontend mode, i find many duplicates of the same infos.

Further more, i’ve already opened a topic but with no response.
I was thinking to set a onepage home with Type 3 header and sticky menu + special header style enabled (basically centered sticky and transparent both logo and menu).
Is it possible?
