Columns Not Printing Out

When I’m at the plugin “Show Options” section, there’s an option to move the content into columns. When I do this, and continue, I get a preview on screen that looks perfect.

However, once I export to PDF, or Save-As to PDF, or do a Print Preview, it always outputs a single column of content. I’ve tried using different browsers (Chrome, Safari, Firefox) but always I get the same result. The initial rendering in browser looks perfect, but the print preview / save as options, always output everything in one column.
