Terrain Detail Mesh wrong texture

Hello, I have problem with Detail Mesh.
When I Add Detail Mesh (to paint some grass), I wanted to use my own grass. (On the left, the pixel one, name GRC)

But when I try to pain with a brush, I get that dark green grass, which is behind with different texture.
I have tried that with another type of grass (GRS, which is on the right) and get same result.

Here I got inspiration :

(just changed material texture)
Thank you. (v2020.3.8f1 DX11 URP)

Ok, solved. Unity 2020 didnt support that … I had to update unity version
