Can't get a published file to play all the way through sound files

Greetings, all

I know I have done this correct before but....

I have a set of PowerPoint files that have instructor notes.  The way I normally handle these is to make the the ppt into a storyline file, and put the instructor notes as learner notes, with narration (text-to-speech reading the note).  Although this has worked for me in the past, I can't get the slide to stay up until the user clicks or swipes, cutting off part of the narration.  Can someone take a look and let me know what I'm doing wrong.  I'm attaching the offending file.

Thanks,

Judith Reymond
