Problems with WP normal generation

The default structure of my wordpress is

<div id="wrapper">
<header class="fusion-header-wrapper"></header>
<div id="main"></div>
<div class="fusion-footer></div>
</div>

I have created a new page that contains a div with some text and two buttons and a contact form. If I delete the contact form the structure is the same, but when I put it the whole structure change to

<div id="wrapper">
<header class="fusion-header-wrapper"></header>
<div id="main"></div>
</div>
<div class="fusion-footer"></div>

Basically what happend is that the footer is taken out from the “wrapper” div.
I don’t know if it’s relevant, but I’m using fusion builder as editor and I’m putting the contact form inside a text element.
