I just found out that when you remove <!--site1-site2-site3--> from the description in one of the languages, it decreases the number of repetitions.
For example, i'm browsing the store in the english language and i have the product "Call of Duty 3 (PS3)" in the category "All PlayStation 3 Games" repeated 12 times when i do a product listing. If i go to admin and remove <!--site1-site2-site3--> in the portuguese language of the category "All PlayStation 3 Games", the product is only repeated 11 times.
I hope i'm getting understood...
