Why are (Pages for Mac) templates, in the Library folder different than what's available in Pages? Mac's Pages templates seem to be stored in: 

Library/Application Support/iWork/Pages/Templates/My Templates


However, when I use Pages and wish to choose a template, what's available is different than what's in the Library folder. 

Can anyone explain this discrepancy? 

Thank you.
The pre-installed templates are stored within the application bundle. You find them by right-clicking the Pages application in the Applications folder and choosing 'Show Package Contents…', then navigating into the subfolder Contents—>Resources—>Templates.

The 'MyTemplates' folder is meant as a standard folder for templates you create yourself.
