Whittaker transitions not normalized

Whittaker has issues I have been trying to fight for several days. I set all the biomes to a white terrain layer (microsplat), the "default" is orange, which should only be applied when there's an unassigned biome.

(Sharpness is set to 0.9 but doesn't seem to remove the issue changing it to a lower number)

There are borders between biomes that appear as default biome. The borders are not between the same biomes, in some places they are different.
