Kleopatra cannot import this Root CA certificate

SUMMARY
***
I have created a certificate for qualified signature with "sign me" which uses D-TRUST certificate chain. I can import my certificate into kleopatra, I can import issuing CA's certificate, but I cannot import the Root CA of said certificate.

Certificates are located here: https://www.d-trust.net/en/support/repository

Import works: https://www.d-trust.net/cgi-bin/D-TRUST_CA_1-21-1_2021.crt
Import doens't work: https://www.d-trust.net/cgi-bin/D-TRUST_Root_CA_1_2021.crt

No error message except that the certificate is not imported.
