When I preview a scene, the second slide plays 2 audio tracks at the same time. There is only one audio track on the slide.
When I preview the problem slide by itself, only the audio track that is supposed to be there plays.
I have opened the wave file for editing and when I play it I only hear the one track. This is all very obvious partially because the 2 tracks are in two different languages, English and Dutch. Weird because this lesson should only have Dutch audio tracks.
I would really appreciate knowing if anyone else has seen this and fixed it.
