Multlingual site: changing language for bilio page not working

I've change the biblio path of my site to /publication. Now when i add a menu link with path "publication" on my multilingual site, i get this error:

Keine Elemente gefunden
Ändern oder entfernen Ihre Filter und versuchen Sie es erneut.

That mean No element founded! Change or delete your filter and try again. It looks like bilio set the path of the site (de/publication) as a search result with no result for the german language. But not for the english language (en/publication).
I've a multilingual site with german an english installed on it. So the url path are changed acording to languages. (/en for english and /de for german). And the bilio path only work for englich (/en/publication) and not for german (/de/publication).
Please help.
