On my HousingUniverse.com main page I am having a problem

On my HousingUniverse.com main page I am having a problem being able to edit the 3 default boxes at the bottom of the page. They are the ones titled "Service Headline"... you can see them at the bottom of the http://www.HousingUniverse.com page. I can't find an area to edit them in widgets or by clicking on the text within the boxes? I get an error that I do not have the ability to access those pages, even when I am logged in as super admin?
