Removing the "more tabs" on header

Hey guys,

I am trying to figure out how to remove the “more tabs” tab on the header of my website. It wasn’t there before, then I added another page and it seemed to automatically add. I can see how this could work if I had many more pages and they wouldn’t fit across the header, but I only have one, and I want the “more tabs” tab to be my tab it is listing when hovering it. see my site-> http://www.phenomglobal.com

Any help is much appreciated.

Thanks!
