Why is Apple referencing CVE-2021-30938 and CVE-2021-30987 in their listing of security updates when they are not searchable in the National Vulnerability Data

Why is Apple referencing CVE-2021-30938 and CVE-2021-30987 in their listing of security updates when they are not searchable in the National Vulnerability Database? Their status there is listed as "* REJECT * DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn by the CVE program. Notes: none.". Can anyone give more clarity what is going on?
