Animation Retargeting Dont Work

Hi everyone !

Some trouble appears when attempting to retarget the ASP’s skeleton with the Mixamo’s skeleton,
I follow this guide : Animation Retargeting (Different Skeletons) | Unreal Engine Documentation
And at the “Retargeting Adjustement” chapter, they said that, if the retargeting goes wrong, i can right click on the bones and retarget it, but i dont have the option “Recursively Set Translation Retargeting Skeleton” as they show.
Furthermore, the retargeting make it very very wrong :

I checked if i make a mistake during the guide’s steps, but i dont thing so,
The original skeleton have at least 2 more bones, one each legs between kneecap and foot
There is bones i couldnt match between both skeleton, here is the pictures of the retargeting manager :

Someone have an idea about what’s going on ?

Thanks for all and have a good day !
