The Recertification section will be enabled on the Edit Certification page only when you have already selected the “Has Recertification” checkbox while creating a Certification. If you didn’t choose the “Has Recertification” option during the Certification creation, the Recertification section will not be available for editing on the Edit Certification page. To enable the Recertification feature, you need to ensure that you select the appropriate option when creating the Certification.
