Material Error w/ Landscape Visibility and Grass Ouput Nodes

The Grass output becomes super densely populated without regard to its settings when I use the Landscape visibility node on the Visibility material.

Here are the landscape material settings.

These are the settings of the base Landscape Material
These are the settings of the Visibility Landscape Material

Now, I copied the base landscape material verbatim and renamed it and then added the Landscape Visibility Node in the material editor to the opacity mask. It works fine, except for the grass output gets messed up in that component I removed visibility.

I’ve tried different approaches to this problem, but nothing seems to work.

Any thoughts?
