Wrong title in Facebook Share

Hi,

The wrong title appears when I share a post. It starts with the name of my blog.
It’s not doing it on every article.
website url : http://carwatcher.fr/
the bug appears with this article for example : http://carwatcher.fr/5-voitures-pour-aller-au-ski-avec-style/

Here is a screenshot of the bug : https://www.dropbox.com/s/se1shhagg3btmv9/Screen%20Shot%202016-03-02%20at%2015.58.25.png?dl=0

Thanks for your help
