Absence Management Email Notification Subject Line not updated with system message change

Our customer wanted to have the subject line in the Email notification that is sent out whenever an Absence is entered via the Absence Management module in Self Service updated.

We updated the 'HR_ABS_NTF_SUB_MSG' system message (this is the name of the message associated with the pNtfSubMsg parameter on the 'HR_LOA_SS' form function) as instructed in the 'Deploy Self-Service Capability Guide'.

We have noticed that the subject line is now updated in both the employee's and manager's work list, and the workflow notification email that the employee received has the updated subject line, but the subject line in the email that is sent to the manager is not reflecting the change.
