How do I change the water level restriction for PCG foliage generation to match my landscape when using the PCG Biome plugin(v0.2)?

Hey! I’m trying out the PCG Biome Core (with the sample) plugin, version 0.2, but I can’t seem to be able to change the water level restriction.
Changing it in ‘BiomeFilter_WaterDistance_Level_Inst’ doesn’t seem to do anything at all, whether in a copy on my landscape or in the provided sample map/level.
Thanks for any help!

Edit: alternatively if someone could tell me how to bypass the global filters, in v0.2 of the plugin, that would be much appreciated, too!
