Issue with POM Material being used as a trim sheet atlas

Hello, all you wonderful people!

I’ve been working on trying to develop a POM material to be used as a detailing trim sheet, utilizing meshes with multiple UV sets similar to what was done here:

The problem that I’m running in to what appears to be a vector calculation problem. By having to set a specific height map channel (in this case, defaulted to the X axis with a red color), portions of a 3D mesh have a weird twisting effect that appear on them. In the case of the video shown here, it’s any POM effect applied at the positive or negative x-axis of the mesh’s normals.

I’ve been searching for a way to get this issue solved, but have yet to come up with anything. Does anyone have any idea on how I might be able to solve this, or should I transfer these details over to be a decal trim sheet instead? Here is the POM Material set up that I am using:
