Notification emails sent out do not have valid URL Link

The emails being sent out to end-users in regards to incidents being created or resolved do not contain a valid link.  For example, the emails being sent out contain the follwoing text:

***

{ResponseLevel} Incident #{Id} has been marked as resolved.  You may use the link at the bottom of this e-mail to view the resolution notes.

Resolution Summary: {Resolutions/Title}

Resolution Details: {Resolutions/Description}

Reported By: {RaiseUser}

Report Date and Time: {CreationDate}

Reference Number: {Id}

Summary: {Title}

Details: {Description}

To go directly to this Incident, please click the link below:

{$ApplicationSetting.ProcessApprover.URL$}

***

The last line is poulated with the following URL:

http://<servername>/WebAccess/object/open.rails?class_name={Class/Module/Name}.{Class/Name}&key={Guid}

This link is not populating with the incidents information and only leads the user to the Self Service Portal.
