Floating NPC during animation

Hi, I have an animation with a hefty amount of keyframes. When I imported it to Roblox, the avatar is floating. I would adjust the torso manually but this is unfeasible due to the number of keyframes. Is there a way to quickly adjust the position of the torso for all the keyframes?

Check export settings in the program you created the animation in. There might be some export option you are not defining correctly. Like a position option.
