Messy page content with this plugin

Hi!

First of all I really like this plugin, makes my work a lot easier, but I really need a little help. If I copy the shortcut of the sidebar into one of my pages, the content of the widget appears fine, but in the wrong place. It pushes the whole content of my page (a picture and text) to the bottom, while the widget is above all that on the right side (it’s desired place is next to the content and right of course.)

I’ve tried adding the shortcut at the bottom of the page, at the top, center, aligned right…etc, but it’s just not working. So where exactly should I put this shortcut? Thanks!
