Audio clips (narrations) are playing on the wrong slide(s)

I've got this problem as well. I will go through and open all of the wrong audio, but in my case there are about 40 or 50 slides of a 187 slide project that are previewing and publishing wrong. (The correct audio is on the timeline, but different slide's audio is being played in the preview/published project) I would have liked to be done with this project by now...
