Unwanted Compfight Attribution Showing

When you go to my website, seanlaurence.com, there’s a list of each post and a summary. The summary is the first few sentences of the post. At the beginning of some of the summaries there’s an unwanted compfight attribution. For example in the post, “For Those New to the Boston Startup Community” the summary says “Emery Way via Compfight”. It’s fine if the attribution is in the post itself. But I don’t want it to show in the summary.

I circled 4 examples in a screen shot here: https://dl.dropbox.com/u/16777087/UnwantedCompfightAttributionShowing.png

I’m using the Compfight plugin and the Montezuma theme.
