Analytics Works On Every Site Except One

Hello, we have a multisite instance and we are using the network wide analytics as well as allowing site admin's to add their own tracking code. Network wide analytics work fine and each site that has a tracking code works fine as well except for one. The site in question is using the same theme as many other sites with tracking codes, and we've waited well beyond 24 hours to allow the stats to update. One thing I noticed is it's only loading one copy of Google's __utm.gif, where all the other sites with a site specific tracking code are loading two copies.
