Creating Animation montage from mixamo

I need help with this animation. As you can see the animation for stand to sit to Idle changes its position. I need everthing to happen in 1 position. I would really appreciate it if anyone could help. thank you.

you can create a blend mask at the first spine joint so that everything below it is ignored

alternatively you can also edit the animation in your 3d program to remove the stand up portion as well
