thelostdutchmann on "[Plugin: Polylang] catagory page not found"

I have a 2 language website but if i put a catagory page in the it works fine for the default language but if I go to english(the second language) the page is not found. I know the problem is in the link to the page because it ads en/ in the link but the catagory does not work that way.
it shows
http://www.u400486.gluweb.nl/duallang/en/category/meat/
instead of
http://www.u400486.gluweb.nl/duallang/category/meat/
how do i remove the en/ from the link.
