Groom height changes?

Hi, I have this metahuman with her groom. I edited the metahuman in my 3d software to make her height shorter and then inside Unreal, I will need to reposition the groom downwards to fit her new height but this create a weird orientation/rotation whenever she is doing animations that require bending.

If I replaced the character with the previous height, the groom works perfectly.

Already have binding but still doesn’t work. So anyone knows the solution?
