Query: No dialogue

I purchased the season pass for season 4. Only episode 13 has no dialogue. All I can hear is the background music and the sirens. I played the video on my iPad and my PC to see if one of them was causing the problem. Since other people have had this problem as well, it looks as though they gave us the video with no sound. Since Amazon doesn't enable captions at all, this makes the video virtually unable to be watched.
