PCG Layered Biomes - Encountering problems with spawning on certain landscapes

Hello. I am currently experimenting with the “PCG Layered Biomes” plugin on the marketplace and have been having an issue where the pcg spawning gets cutoff at seemingly random areas, as seen in the attached image.

The pcg spawning will not even spawn on certain landscapes but work perfectly fine on others, so I am currently under the impression this may simply be a glitch with the current state of pcg. I have attempted to modify the pcg graphs and played with the values in the data assets, but I am seeing no changes even after forcing regen.

To further explain, the colors seen in the image are the debug areas for the spawning of the static meshes and simply moving or regenerating the volume does not work. I would greatly appreciate if someone could offer a potential solution if they can.
