I want to change the Direct Supervisor Selection. But I cannot do this because Validity Period is empty.

As I understand from Community, the Direct Supervisor Selection is enabled from a later release, after our go-live. HCM When the ‘Direct Supervisor Selection’ is set to the ‘Based on immediate parent position or above’, it doesn’t display the employee’s supervisor under the ‘Employment Infor’ section in the ‘Employee File’ page. | IFS Community
When I look behind the Validity Period, it is set to be empty on the view whenever the business_unit_type is 'COMPANY'.
Out business unit has a validity period, but not coming up in the view, because of the selection of the view - Bus_Unit_User_Org_Struct

Is this a bug?
