Your plugin keeps inserting FB script

Hello. Your plugin keeps inserting this script to HTML output and causing an error.

            <script>
                (function(d, s, id) {
                    var js, fjs = d.getElementsByTagName(s)[0];
                    if (d.getElementById(id)) return;
                    js = d.createElement(s);
                    js.id = id;
                    js.src = "https//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v3.2";
                    fjs.parentNode.insertBefore(js, fjs);
                }(document, 'script', 'facebook-jssdk'));
            </script>

I have only this option checked in settings ragarding FB button: Share my blog with friends (on Facebook).
I guess I don’t need this script at all. Can you fix it? It happens on every site I am using your plugin.
