When a job fails an editable email notification is configured to send details as per the default system configurations. This is not happening. These email are being delivered with the tokens not being replaced and it appears they are coming through as a string or text.

Sample email format being recieved:

Subject: $PROJECT_NAME - Build # $BUILD_NUMBER - $BUILD_STATUS!

Content:

$PROJECT_NAME - Build # $BUILD_NUMBER - $BUILD_STATUS:

Check console output at $BUILD_URL to view the results.
