Podcast Template- Adobe Audition - Runs past last clip

Hi, not sure how to describe my issue because I am new to Audition but I am making an intro clip for a podcast and have clips in the host section and music bed section. I have it all perfected and am ready to export it but I noticed when I play the clip back it runs past my last clip (which is in the music bed) and its silence. I'm not sure what this is and why it doesn't just stop after my last clip.

Anyone know?
