Tvheadend

I'm trying to setup tvheadend v3.4 for the first time on OpenElec 3.0.6. I have an HDHomeRun Dual connected to my network. Tvheadend detects my tuners properly and finds about 260 services, but none of the services have their "Service Name" populated and they don't play from the browser. I found some other posts about people with similar issues, but they looked in version 3.4. Is there a setting somewhere that could cause this?
