RA Web: Role Members issued by External CAs states "Unknown CA"

Import as an External CA, for example out internal CA Certificate.
In Admin GUI you can see the CA, download the CA certificate, and you can add role members issued by the external CA.

• Add a role member to any role for a user issued by the external CA
• Go to RA web and look at role members.
• The new role member is visible (as it should), but the CA for the role member says "Unknown CA"

It should be visible which CA issues the role member, instead of stating Unknown CA.

All operations were done using SuperAdmin role, on a local system (no external RA).
