Advanced firewall

How do I block specific ports using adv firewall? How do I modify rules? When I go to rules page…there are small locks on all the rules alonjg the left hand side and I can't edit any of them, maybe just one. Why are they all locked? When I go to app settings, and I click the pencil button to edit the settings for that app, a menu comes up to change the settings for that app. But when I click on the dropdowns to adjust settings…they're all blank, why? What other programs are required to use this program? This firewall is horrible if I can't adjust anything and nothing works…I maybe want my money back but can someone help?
