Material selection question

[RyanJP]

After I select a material for a backsplash there's often two different materials that show up in the "Backsplash Layer Definition" box. I'd only like the one I selected to be there. I'm new so I'm probably missing something, but can't figure it out. 

 

Thanks for any replies. I attached a picture that may help explain it.

Each material is defined in two ways per material, one for Vector View Cameras ( lines and colors only) and Standard Render Cameras where 3D surfaces are painted with a Texture across those 3D faces. Different aspects of the same material for different camera types.

Thanks David! I'm not sure exactly what all that means, but I'll do my research on the info you provided.
