Sprites - Diffuse on a sprite does not render on mobile

So my level whose level tiles have a Sprites - Diffuse instead of Sprites-Default do not render on my mobile Galaxy Note 3. Do I have to change the rendering path? I set the level to that Sprites - Diffuse so that some point lights show up (such as one on your character) and you get a nice glow in the cave.... though yep nothing with that material renders on mobile, it does when the build target is android and it is in the editor. Pc and Web Builds do too... just not on mobile and cannot figure out why.

 

This has to be an easy fix then if no one else has an issue like this and I just don't know the trick.
Anyone?
