Hi, I have problem with the order articles

I want : first top rated but in my k2 in the top site I have last rated : (


I wants to make a ranking of articles but I have a problem.

There is a setting under the category to set the default ordering. Go to edit your category or menu item if you have selected more than 1 category and in the params:
category item layout->other layout options->item ordering-> Highest Rated.

Thats all

probably i have something wrong with my K2 ..

When I have
---> Item ordering ----> hightest rated

I have order

1) article 1 vote
2) article 1 vote
3) article 2 votes
4 article 5 votes
5 article 2 vote

this is the last rating not hightest raded : (
