Ticket Error During SSL setup NW 7.4

Dear Folks,

I am planning to set up SSL for our portal system. But the issue here is in the first step itslef I stuck. The problem is in NWA--> Configuration--> SSL, I imported the wrong ticket and now I want to remove the certificate, but I can't see any option to remove the ticket.

Kinldy Suggest what can be done to remove the wrong ticket. I cant edit any thing in the screen now.

Thanks & Regards,

Satyabrat
