Unwanted Narration

Hi All,

I've recorded a course and one of my layers has rogue audio. What's happening is the audio start with, "The foun...If you've selected incorrect information for the found asset, you will need to delete and create a new found asset." I can't find the first two words ("The foun") anywhere in the audio but I hear it when I preview the slide. This specifically relates to slide 4, layer 8. I've re-recorded the slide and it still is in preview. I also saved, closed and re-opened the course and exported the audio to import it back but I still hear the unwanted narration. Any ideas are GREATLY appreciated!

Thank you,

Beth
