My movie seems perfect when I play it on iMovie, but as soon as I export it somewhere the sound messes up and misplaces itself all over random video clips. How do I fix this?

I have made many iMovie projects before and they have all exported quite fine. Yet, as soon as I export this video somewhere, the audio misplaces itself all over other video clips throughout my project. I feel like I have tried everything. I have stabilized every clip, consolidated the media, went over all of the audio clips again and again... it is really frustrating. Please Help!
