Grass layers are broken in landscape material

Hi. I am having a strange issue. i wanted to add a new layer to my landscape material but when i did that the whole material stopped working and started showing me “Grass maps needs to be rebuilt” (Yes i did build grass maps in build menu and didnt work) so i deleted the layer that i added so that the material could get back to normal but it didnt. now each material works except the Grass and Auto material for some reason. i cant seem to understand the issue here hope someone could help.
