"Duplicate and Retarget Animation Assets" will generate animation sequences that differ from the original one.

Hello.
Please answer the question.

“Duplicate and Retarget Animation Assets” will generate animation sequences that differ from the original one.

In the IK Retergeter screen, the animation is working fine. However, if you export the animation and check the generated animation sequence, the animation is different. For example, a jump movement should be performed, but the height does not change, the size of the mesh is very large or the orientation changes. In the preview screen before exporting, they all worked correctly.
Please can you tell me the cause of this?
