Mixamo animation retarget to metahuman

Hello,

I believe that there is a bug in one mixamo animation which translate to bad retargeting of the animation.

I am using unreal 5.7.2

Steps to reproduce:

Go to mixamo: select animation “flair” (the one where the character stays on the ground)

Get a metahuman of course

Create the IK rig for mixamo and then retarget

On the preview everything looks fine

but then when actually exporting the metahuman starts and finishes with a T pos:

this is bugging me for a while now, I tried with another source animation and the problem is not occuring.

Anyone got on idea ?

Thanks in advance for the help!
