articles and excerpts weird behavior

Hi. I'm using spirit and upfront. I had to import old articles from an old wp site so I copied and pasted the posts in new posts (text and images). Two problems with the same post here.

On category pages (ex: http://www.sopabic-patrimoine.org/site/category/realisations-2002-2003/), date is displayed in english. I have a french wordpress install and french is selected as main language. I was able to delete or edit "written by" , comments count and "read more" using post parts with upfront. Problem here is english date.

But

when clicking on read more , once on the article page (http://www.sopabic-patrimoine.org/site/exposition-de-dentelles-et-de-broderies/)

date is in french (perfect!) but I can't edit or delete the author and comment count using post parts in upfront. It's not available. So how can I delete/edit those ?

Thanks
