Bug in support for editing system workflow message templates

All symptoms of this have not been confirmed.
Potentially user error, however, message templates normally display links to either view the default template, or to revert to the default. This is definitely not happening.

Un-confirmed symptoms of the bug...
It may be that a copy of the template was created instead of updating the template. Changes were made to the template yesterday; today, there is a User Driven template that I'm pretty sure was not there yesterday, or at least before I edited the template. The user driven template does contain the changes I was trying to effect. Client reported today that the default template was still in use.
