How do I disable feeds?

Without intending to, it seems that some of my RSS feeds that I read in a different app have been added to DevonThink. How do I get rid of them? I have looked at the RSS section in the Preferences, but can’t find a place where the individual feeds show up/ where you can unsubscribe.

Thanks!

Just delete the feed(s) from the database. RSS feeds in DEVONthink have an orange, RSS icon and they work much like a Group in DEVONthink, containing the blog entries for the feed.

I know how to delete an RSS feed after it gets into DEVONthink, but how do I unsubscribe to a feed?
