Facebook Share Preview Problems

I am tryin to make work properly the facebook share button, I’ve enabled it through Jetpack and also a “Facebook share” plugin.

When I enable them, and share the ‘share’ only shows the titles but not preview of the content. Not only through the button but if I copy the post url and paste it on facebook does the very same thing. When disabling the share buttons, it goes back to normal.

I think its messing up the metadata or something like that.

Any tip would be useful
