Category link wpml

Hi again 😉

I have a little problem with my permalinks I guess, but no way to find the clue…

When I switch language to enghish (footer area) on my category pages, the system don’t redirect me to the right url.

When I am on my french page :
http://vog-boutique.com/categorie-produit/robes-jupes/

and I switch to english version :
I go to :
http://vog-boutique.com/en/categorie-produit/dresses-skirts/
(–>404 error)

instead of going there :

http://vog-boutique.com/en/product-category/dresses-skirts/
(–> url works!)

thanks!!!
