Articles not showing up the same way

Hi!

Why, in this article : http://passion-lecture.com/salon-international-du-livre-de-quebec-2013/

The name of the author, the date, the tags and “Edit” are written

and why it’s not the same in this article : http://passion-lecture.com/les-ames-vagabondes-stephenie-meyer-2/

The category is the only thing written.

Why? (I prefer the way the fist article is showed on my website)

Thanks!
