Summary of Changes

Wherever the Site Templates are listed in a select field templatestyle it only displays the programatic name of the cassiopeia extended template and not a nicely formatted string.

I don't know why there is no seperate language file for cassiopeia_extended but as the xml description for the template is in in the main cassiopeia language file I have added it there
