Widgets not fixed when content is in shortcode

This is difficult to explain and I don’t really know if it can be considered a “bug.”

I use the OnePress Social Locker plugin (http://ww.wp.xz.cn/extend/plugins/social-locker/) You will have to share the page to see everything I am referring to.

To hide some content until the page/website is shared.

Once shared, the content is displayed, but the “fixed” widgets only respond to the length of content until the beginning of the [sociallocker] shortcode.
