Pretty much the title, I've been trying to load a custom biome for a pretty good little while and it takes an incredibly long time to load (which is probably on my end) but it won't load any of my custom biome colors. I'm not sure why this is, as one of my biomes does seem to work. Attached is the Datapack with both biomes to test out.

Not sure what to do here, but this bug needs to be fixed because these custom biomes will be integral to my server.. 

It seems that people are getting confused that I'm trying to load these as dimensions, I'm trying to load these as overworlds.
