Menu not saving

Hi!
I have two languages installed (ES and EN). ES is my primary language, so my default menu is in spanish. I added aditional links to the menu and selected that they only could be seen in english. The problem is, that as soon as I save the menu, it resets the “display on pages in” to both of my languages. Any Ideas?
