Problem with unknown graphic artifact from Wall Object.

Problem with unknown graphic artifact from Wall Object.

I have this graphical glitch that shows like it's some kind of vectored shadow on the physical wall and angling into a near-common axis point.
I have built and rebuilt the mesh several times.
I have used other creators Normal Maps and Specular Maps to no avail.
I even tried the maps from other Text-style Neon Wall Light CC that doesn't have the same problem I have.
I've even tried a website that makes Normal and Specular Maps for you.
But now I'm convinced it's not anything to do with the Normal or Specular Maps.
I also tried the mesh from other creators and deleted all of their vertices and added my own text and joined it.

But still no solution. It always shows exactly the same result as the sample picture above.
It would be great to have an understanding of what these "lines" are and why they vector into a common point to the right side of the mesh.
I can't even imagine what it is, but it clearly has some logical reason for its existence. Nothing random or anomalous about it.

Programs used:
Blender 2.7
S4S 3.2.0.3 (Star)
Gimp 2.10.28

Type of Object: Wall Light
Created from S4S: Object - Create 3D Mesh
Base Object used: Plank Perfection Wall Light (Base Game)
Base Mesh: Exported the Plank Perfection LOD 0.

Blender processes:
Imported Plank Perfection LOD 0.
Deleted the existing Vertices and added Text.
Extrude Text to 0.0025. Set font type.
Set Text scale and xyz position.
Convert Text to Mesh from Curve/Meta/Surf/Text.
Set Mesh Normals to Recalculate Inside.
Added Modifier: Decimate. Set Planar to 180. (I did also try without including this step)
Scaled S4Studio_mesh_0 to xyz 0,0,0
Joined "Text" to "S4Studio_mesh_1"
Created New Image. Unwrapped project from view.
Saved .blend file for import as LOD 0,1,2.
Deleted "s4studio_mesh_0"
Set Scene Cut to 0.
Saved .blend file for import as Shadow LOD 0,1,2.

Gimp processes:
Created a simple 64x64 white png image for import as the Texture.

S4S processes:
Imported all the LOD and Shadow LOD from the two .blend files.
Imported the 64x64 white png image.
Imported Normal and Specular Maps in Warehouse.
Set Lights to 90 intensity in Warehouse.

My Files:
Normal Map (from the web)
Specular Map (from the web)
TheReds Studio Neon Light.package
TheReds Studio LOD.blend
TheReds Studio Shadow.blend

Keep in mind: I did try several Normal and Specular Maps. Not just the ones included in my zip folder. Maps for several sources and working packages that do not have the same problem that I have.

I've exhausted all my own research and several text and Youtube tutorials on how to make this very simple type of CC object.
But this problem that I have defies logic that nobody has covered or discusses in all of the resources I have looked over.
Your help is greatly appreciated.
