2/ easysocial search filters are not working

and easysocial advance is not working neither

I have verified, there is only one menu alias for "recherche" (search in french) : http://awesomescreenshot.com/0cb2ki2816
and all seems ok with plugins : http://awesomescreenshot.com/00a2ki3t67 http://awesomescreenshot.com/0122ki41c1

can you help in solving this please
thanks in advance
