WPMU site listings different?

Hey guys and gals,

I have two different installs of wpmu running on two different sites. One is on bluehost and the other is on hostgator. The process to set each up was exactly the same but I get two different view styles.

the first you'll see the sites listed with the full sitename.domain.com listing and the second i get just the sitename.

Any idea why this is happening? Anyone seen this before?
