Recommendations: Delete the movies that I already added to "Watchlist" from "People who liked this also liked"

Hey,

I found this information on FAQs http://www.imdb.com/help/show_leaf?personalrecommendations&ref_=tt_rec_lm and I believe they are helpful.

More specifically: 

Why do I see items in my recommendations that I've already rated?
If we do not have any recommendations for you (either because you have logged out or because you have not rated many items), IMDb will show you a list of items that many people have seen so that you can enter ratings to get recommendations. When this happens, the widget will be titled Rate and Get Recommendations instead of Recommended for You.

I hope I have covered this issue enough!
