Timer fails to call email Service Task

Flowable Designer
1

Hi Team,

We are facing a BPMN configuration issue: three timers are associated with the service task (for sending the email). We are seeing the inconsistency—either all three expected notification emails are received, or only the first one, or sometimes only the first and second, not the third one.

Please find the .bpmn and refer to the highlighted red part, where the timer is configured. Also, I have added a configuration snapshot. Could you please explain why there is this inconsistency? and what correction will solve this issue?
