RSS reader

Hello , does anyone know how to do this project: www.github.com/Etuldan/spaRSS be programmed from appearing articles in the category of " entries " (all_entries) several times - the problem arises when the few items on the menu (feed list from OPML) is displayed article that is the same and has the same url so happens that in the category of " entries " Article simply display will appear several times.

I want to make this article in "entries " displayed only once.
