Hi I have the same issue. I tried deleting it as I wanted to reinstall it.
Apparently, text within the column brackets dont appear and the columns dont take effect unless they are viewed in the post link.

(only if you click on TEST, will the columns show the text and take effect)
Hope this helps in your quest to making it better (but i really love the plugin and have been using it since several years ago!!!!) THANKS
