The "Home" Link does not go to the current home page

Hello,
I am working in the Blue Zinfandel Theme. At first, I used a static page, but now it is set to display current posts. When a visitor goes directly to the site (http://www.unitedcreditunion.org/), the home page displays correctly. If they click on the "home" link on the main nav, it adds a different link (http://www.unitedcreditunion.org/united-credit-union/), which displays the old static page.

Where do I change the "home" link?

Thanks for your help!

Julie
