How to remove Link to original source in Autoblog

I have installed Autoblog and understand that you can insert anchor text into it to link to original source. I actually do not want to link to the original source (I'm actually providing the content and using autoblog on my multisites to pull in the content, my work around on not being able to "push" my content to my sites)

Anyway, I've left the box blank but it still enters the source.
