Blend Space Animation not working properly(?)

Hi! I’m trying to create a new Overlay state (Sword) to add to ALS (Advanced Locomotion System v4), I’m following the steps in this video:

Everything seems to work (the Idle animation changes from the default one) but the legs are weird. It’s fun at first but I can’t seem to solve it. Has anyone had similar experiences or knows how to fix? Thanks!

I got it, it was an issue with Foot IK. Just go to animation, add Curves (Enable_FootIK_L and Enable_FootIK_R), then I added a key of time=0 value=0 to each curve. It worked.
