Paint Layers Not Showing After Making Landscape Material

Alright, I can’t seem to move forward in my Project. I followed several different tutorials to tray and solve this issue, even going as far as re-making Landscape Material several times. The problem I’m having now is the Target Layers are blank. At first they simply had a Question mark, but now there is nothing. I selected “Landscape 1” and then under Landscape Material I clicked the arrow and the Terrain I made was placed properly. Then it all turned black, but not just that, but there is no Paint Layers to work with. I did “Rock”, “Dirt”, “Grass” and a few other materials on the build. But nothing is showing up. I will provide some pics, I would appreciate any help, Thank You.
