Problem with pinnacle studio 9

[matrix man]

Hello everybody,
I have a problem with this program regarding two chapters in my final movie.
while editing the movie i added chapters along the movie.
whenever i press in the menu on the specific chapter (one of the two) then a sound is heard that is irrelevant to the sond of the chapter and the strange thing about it is that in the preview i don't that sound.
thanks for the help,

Pinnacle Studio is full of bugs like that. Be glad your bug is a minor one. Wait until you've spent hours setting up a complex video with lots of cuts and transitions -- and then the program starts messing up and crashes. And then you find that it autosaved your project with whatever errors it made so you have to start all over again.

so what can i do in order to fix this bug?
