Problem with folliage tool cursor display

Hello
Does anyone know why does my folliage paint brush suddenly looks like this? Lit vs unlit.
Its happening in any level inside same project. Its ok when I open a different project

The painting seems to be working, I think.
It looks like there is something wrong with some system shader or something?

I migrated the level to a new project and the problem is gone.
Maybe I must have messed up with the system shaders or something?
