how do I add options to the wdfb_like_button shortcode?

Hi, I try to use this shortcode wdfb_like_button for a like button but when I click the generate like button the comments form opens but it is not totally visible.
Here's the page where I get this error:
http://biz139.inmotionhosting.com/~dylann5/wordpress/class-pricing/

Is the first like button on the left under Follow Us.
Thanks!
