RSS feeds auto downloading and script

I started using the Feeds script in DT Pro, but I ran into a problem with one of them. The NY Times feed downloaded the articles, but then after closing the database (and going to the tutorial for a moment) and then re-opening it and selecting that folder, DT re-downloaded the NY Times headlines, so now there’s two of each. Why would that happen and how can I prevent it from happening (so I don’t have to delete duplicates all the time). Thanks.

I’m thinking of using this again for select RSS feeds, but no one replied to this thread. Any thoughts/insight? thanks.
