signing cert is not listed

Hi,

i have a s/mime cert with key usage keyEncipherment and digitalSignature.
I cannot sign with it and i do not know why.
When i open the user preferences it is only shown in encryption certificates but not in signing certificates.
Has anyone a idea what might be the problem here?
Thanks for your help in advance.
Here are a few screenshots:

It looks like the certificate does not have an associated private key
(otherwise a green lock symbol would have been shown on the certificate
overview page).

If you want to digitally sign with a certificate, you need a cert with
a private key.

Kind regards,
