Metahuman Machin Learning ML Deformer problem

I made a simple cloths animation in houdini and used metahuman houdini plugins and brought back the animation into unreal. i just import my animation and choosed bse skeletal mesh from metahuman. animation imported correctly . I also imported alembic cached of my cloth simulation.

then i ran ML deformer for training everything is working unless frame 64 and upward . always my mesh looks weird and misplace . i can actually see the vertex delta is weird after that frame number. in viewport everything about animations and cache looks same and normal. why is it happening.
