Mixamo animation looping

In the project I’m working on we include the mixamo animation pack so we would have to spend less time working on animations and more time on other things. We’ve noticed, however, that any of the looping animations from the mixamo pack seem to have a weird hitch at the end so they don’t look right when they loop, as if they’re missing a few frames or something. I’ve seen a few things on the answer hub about right clicking the animation and selecting “Add Looping Interpolation” but that doesn’t seem to fix the problem. It’s noticeable on the original meshes but seems to be even worse after we retarget them to our own meshes (possibly because we have a cartoony style with more exaggerated features). Is there anything else we could try to get these to loop correctly?

Im trying to figure out how to stop the loop. I put key frames in and j cant seem to get it done
