Release or EnvironmentObserved from Tokyo release.CauseThis is by design. Even though the schedule template specific the period of the 'Do not Repeat' schedule has a particular period, it is not a real time period. The time period in the template just clarifies the time period, which means, even though the shift creates the schedule 2 years after the end time, the schedule still is generated with the same time period. Even though the shift is assigned to a particular person, the duplicated schedule is still active. In this situation, once a call comes in, the processor only gets one notification.
