Signing Certificates in UI Results in Invalid SAN Names

[nebukad]

I am trying to create Certificates with the UI in TrueNAS Scale Version "TrueNAS-SCALE-22.02.0.1". I created a CA, a CSR and signed the CSR with the CA. The UI is in the following state:

The problem is that every time I create a certificate the SAN name gets an extra DNS added. To my knowledge the result should be "SAN: DNS:vaultwarden.home" and not "DNS:DNS:vaultwarden.home". The issue leads to the following error in the browser:

Is this a bug in TrueNAS Scale or am I doing something wrong?

Thanks for your help.
