Question regarding parallax occlusion mapping node not working

Hello. I’m currently trying my best to use the built in parallax occlusion map node for HDRP. On flat surfaces (The basic unity plane) the parallax works correctly.
However, on every other object type, the parallax doesn’t seem to work at all.

Can anyone help me fix this? I’m not quite sure what I need to do.
Heres the shader graph.

It wont let me embed more than 1 image, but if I could I’d show what I mean by it not working.

If you download the Feature Examples sample from the Shader Graph package in the Package Manager, there’s an example of Parallax Occlusion mapping - and the shader has standard normal mapping as well as plain parallax mapping as well. That might give you an idea for how it’s intended to be set up.
