I'm going to run some tests today in Unity, weirdly enough I've run into this same issue before with a model I commissioned before it's something to do with NLA Action Strips, and it's always the last animation on the list. I think I know what's causing it and I will patch it by the end of the day so you can just re-download it.. My apologies for the "jank" :) I appreciate you pointing out so I can make the pack better.
