audiobooks not working properly

I'm doing a software restore on my ipod touch right now but I transferred all my files from my old computer to a new one and when everything was working fine I found a problem that in my audiobook when I start up a book normally it does it thing by "your listening" but then when I swipe to the time I needed on screen it moved but the audio didn't change at all so I removed the books and reinstalled them and problem what am I doing wrong?
