Attestation (System Entitlement Memberships) Deny decision does not remove the membership from employee OIDM - 8.1.2

Hi,

I created a custom Attestation policy from the copied of System entitlement memberships attestation. I triggered the Attestation policy on an employee.

I selected Deny as the decision. However, the UNSGroupB does not removed from the employee's UNSAccountB.

I have checked through the Configuration parameters - QER\Attestation\AutoRemovalScope\UNSGroupInUNSGroup\RemoveDirect is enabled.

May I know where else I need to check, in order for the membership to be removed from the employee, after the deny the attestation?

Thanks.
