Grass And Wind Blueprint Not Properly Working

The wind workd perfectly fine but the grass doesnt look like grass, It looks like alot of plane’s.
I’m not sure what I did wrong but on the pictures I was copying the blueprints from there’s a few problems that I couldn’t sort out.
On my blueprints some of my links, Connected to Opacity, Opacity mask and Subsurface Color are all grey and on the pictures they are normal. I dont know what I did to have them go grey but I cant seem to get it to go to normal.

Another problem is with the wind machine area, On the picture the guy tells me to change some of the texture samples,
First some says: Change normal map for Noise Texture, the second one says: Change Normal map for wind texture’s.
And at the end theres a lerp that says: To wind normal map splitting and world position offset.
I dont know what he means as I am very new to the unreal engine.
The first attachment shows the picture of the persons blueprint I was copying.
The picture below is the blueprint I was trying to copy.

Does anyone know what I did wrong?

I know that the question has been asked for a long time but maybe I can help some people. You are not using the opacity mask!
