Entire avatar moves with head movement but only in VR

So I’ve been working on my very first avatar since I got VR but I’m having issues with it in VR mode. On desktop mode it’s head moves fine but in VR looking down causes the entire character to float up into the sky and looking up causes it to sink into the floor.

I’ve always made avatars for desktop mode but now I want this avatar to work in VR, but I can’t seem to figure out what is happening.
