Update: Added screenshots as proof of my issue.

First thing: Even if the biome is not located in the minecraft namespace?

Second thing: That also doesn't address the issue that the biome won't show up as an option when creating a single biome world.

Also, in my custom predicate (that being kohreth:in_cursed) referring to the biome as "kohreth:cursed_lands" has so far worked for negated predicate target selector arguments (i.e. @e[type=cow,predicate=!kohreth:in_cursed]), but I'm yet unable to find out if the direct matching is functional until I can get an instance of the biome to generate.

I've begun experiencing a very similar bug in Java 1.16.3 (albeit while attempting to overwrite the dimension_type settings of the overworld to allow the use of the respawn anchor through a data pack), where attempting to set my spawn point on a charged respawn anchor in the edited overworld doesn't even output the "respawn point set" message to chat. It's to note that the anchor doesn't explode either, however. I've attached my own dimension_type settings file just in case it would be helpful for this related issue of mine.
