Required fields are not translated properly

Hi,
I am translating some terms locally in my development site.
When I translate any field that is required, the little red asterix (indicating a required field) disappears. It is replaced by "!Requis" (which means "Required" in french). See screen shots.
I am guessing Drupal cannot interpret the "!Requis" string. Is this a bug?
If my guess is right, I think it would be best to reset the "!Required" string as it was originally. Am I correct? Where would I do that?
I attached some screen shots for clarity. One shows the original page in english. The other show my translation pane and the resulting screen in French.
Thanks for your support!
