iMovie cutting the end of my audio

Hi, can someone help me, with this very very annoying issue I have with iMovie. I'm making some videos where I take an MP4 video I've filmed and then I'm taking an MP3 file and using as sound. The sound and the clip are both exactly 13 seconds long, but for some reason, iMovie keep cutting off the audio about 1 second before the clip. When i delete the audio from the project and add it back again it cuts again on a different place. So I have to keep remove it and add it back until it stops cutting it. It's as if it sets the cut at some random point between the end and up to something like 2 seconds before the end of the clip. How do I fix this?

Kind Regards Ben
