Email notification for the transaction Change Working Hours

Summary:

It is happening only with transaction Change Working Hours - After 24C has been applied user receives the email notification hours after the completion of the transaction. It never happened before 24C, and I would like to understand why it is happening. If the transaction has already been completed, what is triggering this FYI hours later? How can we disable this notification?
