People ratings

There have been a few people rated that I decided I wanted to delete my ratings of them, but for some reason they still show up in the recent ratings. e.g. There are certain actors who have different spellings of names, and because of this there are duplicates. Since I don't want to rate people twice, I would like to remove some of the duplicate ratings but they are still there in my general ratings list, just without any stars.

Does anyone know how to remove people ratings from the listings once one has been accidently rated?

When rating "fictional characters" there is now the option to remove the rating, but with "people" ratings there is still no option, the stars ratings can be removed but there is still no way to remove them from being regarded as "rated".
