Why is my Mixamo character's root motion different after importing it to UE4?

Hi,
I’ve downloaded Mixamo characters with root motion but after import to Unreal Engine 4 it doesn’t work properly. You can look on this video: - YouTube

Please help me.

Thank you,

The Mixamo Characters don’t use the standard/default skeleton, maybe it’s because of that?
(as it appears in their store page> NOTE: These characters and animations are not on the standard Epic skeleton. )
