Accordion Spry Problem

I have a problem with accordion spry. I inserted an accordion in my home page originally it worked but as soon as I changed some info in properties panel it got bad, means when I preview it all panels are open and they don't fold. It seems I changed some thing in it's rules, because even when I delete it and save it as another name it still is the same. what should I do? I am new in dreamweaver help me out.
