What causes this issue?

You attempted to import a private key into a PSE. You still need to
import one or more public key certificates.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If the traffic light is red, you need to select and import one or more
additional public key certificates, until the certificate chain is
completed with a self-signed certificate.
To select the certificate, choose the <ZK>Import Certificate</> button.
Select the appropriate file and import it. You can perform the import
repeatedly, until the certificate chain is complete.
&NOTE&
A PSE always contains only one private key, whereas, for example, a
filein PKCS#12 format (*.p12) can have multiple private keys. If the
PKCS#12file contains multiple private keys, you need to select a key. To
do this, open the selection list in the <ZK>Private Key</> field, and
checkwhether additional private keys exist. Select the desired key in
the selection list, and import it.
