Unable to see asset in terrain using Painted Grass texture

I am curious as to why I cant see grass I paint on a terrain to appear unless I am really close. However, if I chose to basically insert the grass as an asset, I can see it in my scene. Also, I have noticed that painting a texture of say, grass in the scene or a tree, The grass or tree does nto appear until I get close. But if I was to apply the grass or a tree as an asset into a scene I can see it in the game view regardless of the distance. Can someone explain to me why this happens?

It almost seems placing it in the scene is better than painting them on the terrain using the texture brush.
