Links are Wrong in Header.php

Minor link issue, that i know is a simple fix...

My site is http://fastlubemarketing.com

In my navigation there is a Blog & News link that I edited, but it seems to point to:

http://fastlubemarketing.com/blog

On the back end I dont even have a "blog" page, via the "reading" settings, my posts page is set to http://fastlubemarketing.com/fast-lube-blog/ which is the correct page.

Why does it not work from the main link, and where can I fix it?

Thanks!
