Floating feet in retargeted animation when using Bridge

Malachi

So I've got some real nice dance animations (the Mixed MoCap Dance Set 2) and I'm trying to get them to work on a Gen 8 character that's imported using the DazToUnreal Bridge. For some reason, the feet are floating off the ground when the animation plays, and are kind of jittery. I think it has something to do with the IK stuff not animating correctly but I'm not sure.

The dance animations themselves are for UE4, but I can retarget those to the UE5 Mannequin with no problem. But when I then retarget from UE5 to the Gen8 figure, those feet just aren't working properly.

Does anybody have any clue how to solve this?
