PSG (procedural content generation) add psg to landscape, don t show grass

I have to levels with different landsacpes, In the first landscape my grass is shown, but when I move my psg to the other landscape only the broken branches and rocks are shown but not my grass, I use a surface sampler to connect it to the landscape node to project it, the only error is that it does not It shows my grass on the second level with the landscape, what could it be? I pass my images with the nodes

This image is with the first landscape where it does show me my grass

This is my graph, but as I mentioned before, it only works on one level but not on the other.

and in this image it is from my second landscape, and as you can see, my grass is not shown, what could it be?
