P384 Client Certificate incorrect issuer CN

We are trying to import P384 Client Digital Signature certificate to meter and we are getting OtherReason. The reproducing steps:
1. We import successfully in meter your P384 Root CA Certificate that has CN=Root CA 384.
2. We create P384 Private key and use Get Certificate.. from context menu.
3. We select Digital Signature and enter Client System Title and create certificate.
4. In Certificate tab we use Info.. from context menu.
5. In Info window it shows that Issuer CN=Root CA 256 and this is the reason meter rejects this certificate
because it checks Issuer CN and expects Root CA 384.

We think that when getting P384 certificate from P384 private key issuer CN should be Root CA 384 and not Root CA 256.
When we use P256 everything works ok.
