Keynote song from Music stops in the middle of the same slide.

Hi. I want to add two songs to my Keynote presentation to play over two different sections of my presentation, which is about 35 slides. Each slide duration is 5 seconds, and set to run automatically. I added the first song untrimmed from Music for the first section, but the songs fades out and stops 2 seconds into the second slide. I tried a different song from Music and it stops at the same spot in the second slide. I work with a copy of the original presentation because I don't want to screw up the original file until I can get the music to work. I have reviewed all of the attached settings and I am playing the songs untrimmed. I'm at a loss as to why this keeps happening. I appreciate all replies.
