I encounter a problem when I configure the settings of the firewall of KAV6.0 for windows workstation.
Generally speaking, the rule entries should be listed according to their priority, but I cannot restore their orders to the standard order after I clicked the "Action", under which either "allow" or "Block" is displayed. After one rule entry is selected, I cannot click "Move Up" or "Move Down" buttons if I want to change its priority.

How can I resolve this problem which confuses me for a period of time.

Many thanks in advance.
