Animation Editor glitching with custom rig

I am having a problem with my rig on roblox studio. I have checked the hierarchy for months, and it is all correct 100%, it does not use bones from blender, just the classic roblox style using motor 6ds, however, in the animation editor, here is the problem: When I try to move the lower torso, let’s say 2 studs left and back, the humanoid root part moves 4 studs left and does not return unless I go 2 studs right and 2 studs back. It has no problems playing the animation in-game, it’s only a problem with the animation editor not working. Do you think that you can help me fix this? Btw, mp4 files don’t work when I try to show them.

Custom rigs suck. Don’t use em.
