Working Hours change on change assignment page impacting duplicate entry on absence duration

Hi All,

We are facing an issue on duplicate absence duration hours. Which is occurring when employees working hours are changed through change assignment redwood page, system is creating one more entry of work schedule on back end table which is causing the issue of duplicating absence hours.

As a alternate person management has been utilized but person management is temporary solution which is advice not to use for any transaction after redwood.

Is there any else facing same issue or faced it. Kindly please let me know what could be the issue.
