Facebook Share and Like Count are always equal

I notice that when user clicks like button, the count number increases. If I refresh that page, the share and like count numbers are equal. This is a bug i think. Pls check it.

Hi!
As I can see like button works properly even after page refresh. Anyways, this is an embedded plugin from Facebook. If you suppose that it doesn't work properly you would better contact Facebook developers. Moreover, you may easily change or insert another code instead of the existing one on page Rose --> Social Buttons --> Facebook Like Button --> Edit.

Thank you
