I've installed Custom sidebars PRO properly (Uninstalled free version + re-installed PRO versio

I've uninstalled and reinstalled the correct PRO version of the Custom Sidebars plugin and the "clone" button is now working. However, when I clone a widget, it is only cloning the actual widget meaning that the content within each widget has to be manually typed. This isn't what was shown in the video describing this feature and doesn't really save any time.

I'm sure this isn't how it is supposed to work?
