Free extensions for Joomla!

I am using Joomla 2.5.7 with Joomfish 2.5.0. and XMAP 2.3.0

The site is bilingual English/French, the original language being English.

XMAP works fine in English.

In French some of the entries (not all) are duplicated and I cannot figure out why.

For instance I have the Sites Web duplicated and here are the 2 links, they point to the same page.

Any help would be appreciated
