Company CA Certificate > WiFi

My company has its own CA certificates to access to Wi-Fi. I have successfully imported the two certificates to my Z30 from PC (Win 7) as listed under docs.blackberry.com/en/smartphone_users/deliverables/47561/als1342708099072.jsp
One certificate - AddTrust External CA Root - imported under Certificates - Authorities but the other one which IT says I need to use - COMODO High-Assurance Secure Server CA - imported under Certificates - Others.

Now, when I go into Wi-Fi configuration for the company wifi network and choose CA Certificates under Advanced Options, there are only Certificates from Authorities. I cannot choose my company certificate, which is listed in Others on the Certificates list under Settings > Security and Privacy.

Do I need to change some other setting to allow selection of certificates identified as Others?

Installing a root certificate on your device - How To - BlackBerry Z10 Smartphone - 10.0.0 and Troubleshooting BlackBerry 10 Wi-Fi Issues | Inside BlackBerry Help Blog have a read of these too.

Thank you for this information, but unfortunately I have read these and tried all suggestions without success.

Devices updated to the latest OS? Can you tell us what that is?
