Unable to cleanup PKI, error file not found: CADescription

When trying to clean up my PKI by running certutil -deleterow 31/12/2018 Cert I receive the following error:

No certs have been cleaned although there are more than enough that should be cleared.

you have to keep the date format at "certutil -deletrow %date% Request" command same as your request submission date. Example: in my failed request the Request submission date was: 2021-01-12 I run the "certutil -deletrow 2021/01/12 Request", and it worked, all failed requests till January 12, 2021 have been deleted/cleaned up.
