first of all I don't see a bug because you picked a random animation to slot into a 3rd party blend... I see UR trying to figure out how to rendor this animation

go back to the basics and look at where your character starts in the first few frames i.e, is he 5 foot up in the air? try a different blend that starts on their feet or any of the loop animations are normally easy to blend
