Compatibility with Fast Secure Contact Form

Hi.
I was trying to insert a contact form made with Fast Secure in a page with a template 2/3+1/3 as follow: http://www.screencast.com/t/ftI4HtAtY. Unfortunately, I noted that the spaces between the boxes in the form are bigger than I expected (look at the red arrow). In fact, if I put the same form in a page or post not using Visual Composer, the space is no more so big. Here an exemple http://www.screencast.com/t/okIgkLNysEa. How is it possible? Thanks

Solved! =)
