Defence+ pop-up decision undo

hello everyone at comodo, i have a minor problem if anyone can answer it here. i didnt know what defence+ was after installing the 3.0 firewall i set the installed options so im prompted with pop-up notices till i get use to using the security software. the problem is i made wrong defence+ decisions that need to be removed or resetted. i found the window that shows the location of defence+ decisions made (not logs) i deleted the wrong entries rebooted the computer defence+ still enforces the deleted wrong decisions i made. my question is how are wrong defence+ decisions completely removed without reinstalling the software.?

delete the rules that affect the executable you have issue with.
