Supervisor not showing in SSHR after update in core HR

hey guys,

i have updated a supervisor in core HR of an employee, after updation, I go to employee's SSHR, in SSHR the employee's Manager field is showing empty.

it used to show old the supervisor but since updating the new supervisor, the field is empty, although in workflow's of applying leave the supervisor is shown in the hierarchy and workflow is running all good.

can you help me out in getting the new supervisor name in Manager field in SSHR.

thanks and regards
