Terrain tool Shift+left click doesn't remove the texture painted


I am following this tutorial Getting Started with Landscapes | Live Training | Unreal Engine - YouTube , and using no-weight-blend when I SHIFT + LEFT CLICK to remove what I have painted over my grass texture it doesn’t remove anything.
When I paint it just keeps layering.

Had this problem, solved after unchecking “Use target value”
