[Plugin: Slick Social Share Buttons] FB likes only visible, if I like it myself

Hello,
I am using Slick social buttons and I have a problem.
I am getting many Facebook likes, but I can only see the number of likes, if I like the article myself.
I am interested in the numbers of likes, but I do not want to like my 500 articles.

Can someone tell me why I can not see the number?
What can I do?

Thanks in advance

regards
Julian
