IKRetargeter has different result in Animation vs the actual retargeted preview

IKRetargeter has different result in Animation vs the actual retargeted preview. All retarget root, retarget fk , and retarget ik are checked on. One of the wrists ik i had moved over to make the hands meet in the ik retargeter preview. The final exported animation however does not look like it does in the ik retargeter preview. Can anyone tell me why? See screenshot.
