What's wrong with my running animation?

[Omnishade]

I made a running animation for magic in left hand from NickNak's rigs for Blender 5.x and I'm using Blender 5.1 - https://www.nexusmods.com/skyrimspecialedition/mods/118525

It looks good in blender and exports successfully but in the game the feet moves outward during the forward motion, making it look really goofy. What can cause this? I've baked the animation and also tried to replace the xpskeleton in the hkxexporter folder with the latest version I'm using, but then I got an export error so that's not working. Can anyone who knows animation for skyrim take a look and see what is going wrong here?

 

Note: This is for female characters and would look even more strange on males.

I've uploaded the blender and hkx files. You have complete freedom to work with them in private as you see fit, but I'm not giving permission to upload or share publicly without my consent, even in its current stage.
