Landscape Material - Lerps nodes bug

The Landscape material loses textures when I start using the two lerps nodes. [Screenshot - 1]
How to fix it?
I’ve already tried to replace it with the material function, but the same result.
But, but when I tried to delete or connect the lerp node straight to the multiply node, all for some reason starts working,
just freakin magic outside of hogwarts. Screenshot - 2These lerps nodes don’t work only on Base Color attribute, but others like a normal, roughness, and specular are ok.
Any guesses?
