[Plugin: Facebook Comments] [plugin: facebook comments] appearing twice on post

Hola!
I’ve installed Facebook comments – and set up the Facebook app – and now I do get the Facebook comments to show – but they’re showing up twice.

Here’s a link to an example post: http://campbellduke.com/2012/01/resume-writing/

Any ideas on what’s happening?

Cheers,
Beth
