Hmm, not sure. Did the CA chain change in between the issuance of the 
two certs?

Adding a new certificate shouldn't affect the trust of any other certs 
so I'm not sure what happened. It could be that those subordinate CAs 
were loaded the first time incorrectly but weren't used so it wasn't 
noticed, I'm not really sure.

In each NSS directory there is a pwdfile.txt which contains the PIN for 
the internal token. You can add -f /etc/httpd/alias/pwdfile.txt to your 
command to list the private keys.
