Browsing to "File → Properties" shows the template file that the particular configuration file is referencing:
ACE comes with a "DefaultTemplate.xml" file that contains the latest configuration objects that were available when the software was released. If new features or protocols are developed before a new version of ACE is ready for release, you may need to manually update your "DefaultTemplate.xml" file to take advantage of the new features. Refer to the Updating the RediGate's DefaultTemplate.xml documentation for guidance on manually updating the "DefaultTemplate.xml" file.
