Biblio entries on users profile don't show by year but by creation date.

Hi, this is the first time I'm trying to solve an issue by searching (and reporting the issue) here, I'm new to Drupal... If I'm doing anything wrong, bear with me.
Anyway, I have had a problem with our biblio module (which we love and use a lot, by the way) for some time. We have the setting 'sort by year', so the articles are sorted by publication date, and this works fine for the full list, but in the users profiles, the lists are still by creation date. Could this be a bug in the module?
