Permalinks/Menu Trouble

Hi,

I am having trouble with our menu/permalinks.

http://psi.expertnerd.com

I have the permalinks currently, set on Numeric. I was using /%category%/%postname%/ but I noticed that when you click on say “Company” or any of the sub pages on the menu, and clicked on Home, it would go back to the parent page of that section. For instance, clicking on Fabrication then Gallery, and then clicking on Home, takes you back to the home page of Fabrication and not the real home page. Any help would be greatly appreciated. I have spent hours on this with no results.
