3642758 - Message No. TRUST057: Issuer certificate missing in database for CN that is not in the certification path.

When importing a certificate response in STRUST, message No. TRUST057 is displayed.
The issuer certificate missing in database display a CN that is not in the certification path.

For example: 
The error message displays CN = Certificate_D, but when opening the .CER file of the certificate this certificate is not in the path:

Clicking on "View Certificate" for the root Certificate_C it appears as it is signed by itself.
However, by isolating the root certificate into file, it is possible to see that it is actually signed by the missing certificate (Certificate_D)
