The Zen Grid Framework 4 templates work slightly different to standard Joomla templates when it comes to duplicating styling. 

In standard Joomla templates you can use the save as copy functionality in the Joomla administrator however in Zen Grid Framework 4 compatible templates due to the way that we store the template settings this function is not available.

Instead, in order to duplicate the settings from one template to another template it is necessary to use the Load Existing template style functionality which can be found on the options > overview page in the template settings.
