[Plugin: Contact Form 7] Contact Page in Navigation

I have added Contact Form 7 to the Contact Us page of my site; http://leothemarketer.tigermanenterprises.net/. I then added the page to the MainNav menu which handles the top navigation menu on the site. Unfortunately, the short code which invokes the contact form on the page is also shown on the navigation menu. How do I remove that code?
