Engine messed up legs in animation!

Hey everyone!
I have a problem. I’m currently using 4.21.1. I have an Adobe Fuse CC character and anims from Mixamo. On the Mixamo website everything looks normal but as soon as I import everything into ue4 the legs of my character are pretty messed up no matter if crouching, walking or sprinting. Did I do something wrong?
It would be great if somebody could help me out!!
Thanks ~!
