I’m having the same issue, but I also have a little more.
When you enable via the checkbox on the page, it shows just fine, but is below my social share buttons, which are done through the really simple facebook share plugin. When I put a shortcode in, even with the checkbox off, I get two of the reviews and butons, however one is above and one below the social buttons.
Right now, I’m just using the checkbox, however the content is now below the social buttons, which on every other page are at the bottom.
I would like to be able to use the longer short code so I do the read more and all, but until this gets sorted, I can’t. Like the plugin otherwise.
