Thread:Project:Support desk/Infoboxes showing tags although all templates are exported and installed/reply (12)

If you enclose the  template call in   tags, you will find that it works (albeit without the CSS styling, which you will need to copy in from fr:MediaWiki:Common.css).

Your modules are producing identical wikitext output to those on French Wikipedia (according to Special:ExpandTemplates). I think the modules have a bug which manifests itself on your wiki, but which is not seen on Wikipedia because of some aspect of Wikipedia's configuration. Possibly HTML Tidy is having an effect.
