Bilingual categories not sycning

I have a bilingual blog (aventurasintimas.com) and I can not change the category name of certain synched categories. For example Amor and Love are synched categories. One is the spanish and one is the english. But it keeps appearing as Love @en on the menu. I go to categories and change the name in the categories menu options. But I click save and the change does not apply. It says "love @en" again instead of "love".
ARgh!
