It is technically impossible to shorten certificate for one particular product, leaving the rest of products in the certificate intact.
If one product should be removed from a certificate, please, do not try to shorten the certificate for this product, because the database will shorten the validity of the whole certificate. Please, contact the Customer Support for this issue and ask to lift certification from one product. Please, also indicate whether the product should stay accepted and will be certified later, or it was certified by mistake, for instance, and should be de-accepted.
