Reproducible: Always Steps to Reproduce: 1.Open Preference-Advanced-Encryption, and [View Certificates]. 2.Navigate to "CNNIC ROOT" and [Delete...], confirm the dialog appears. And, this certificate disappears. 3.Close and reopen "Certificate Manager". Actual Results: The "CNNIC ROOT" which I deleted in step 2 appears again. Expected Results: The cert should be deleted.
