replay audio & visual bug after export

Its not 100% consistent but I noticed today after exporting a clip the audio from towards the end of the clip overlaps into the very beginning of clip as well as a few frozen frames from that same spot, interestingly enough the audio and frozen frames at the beginning are not from the very end but in this case its when my character bails.  Forgive me for not explaining this well, its not easy lol.   

I exported in both a normal speed and a 4x slow motion and the same issue is in both versions if that helps.    

Attached are two clips. the full length clip where at the start you can hear the board clanking on the ground as my character bailed which doesn't actually happen until later into the clip and another version I slowed down to 10% to see the frozen frames.
