FB like button + [wdfb_like_button] appear in the slide in


I have created a slide in on my site displaying at 50% of articles (www.positivox.com) it is set on widget to display a FB likebox i'm using the one provided with the theme.

The problem is that under the likebox there is FB like button + [wdfb_like_button]

This shouldnt show up,
and for the sake of it, i also wonder what is the like button number refering too as it isnt the article nor the number of FB page like.

Also is it possible to adjust the size of the slide in
