Terrain Painting Issue

I keep getting blocks even though its painted with grass and another material. It stays there even after the compilation of shaders. Help??

Please and thank you.

Could you post a screenshot of your landscape material, please?

i removed them and limited myself to 5 instead because I heard another thread saying no more than 5 will keep it from having more issue. Is it true though?

I have the same exact issue however mine happens when I mix 2 ( out of 4 ) specific textures which is weird and even more so I followed a tutorial using the same exact textures in the same exact way and he had no issues but I simply couldn’t mix lush grass with rock.
