Changed Calibration Manager able to see Employee under Direct Reportee

Hi ,

There is change in Calibration Manager of an employee, when we go to employment info of an Employee then Old calibration manager is not appearing.
however when check for Calibration manager record under Employment Infor, under direct reportee , Employee is seen.

I ran Employment diagnostic on employee and Manager record in Report /Validate mode, also ran Refresh manager hierarchy process , but issues has not resolved.

Does anyone has come across such kind of issue and know the solution.

Thanks
