Can't add configured features to biome gen

[janMitame]

I've got my features configured, but I can't add them to the list of placed features. I tried manually typing them in but when I load the pack it gives the error "Datapack Verificaton Failed". Anyone know how to fix this?

edit: I tried removing the list and just not having any features and it still isn't working. aaa
edit2: anything with the fairy namespace isn't working. I can't even add the fairy:fairy-forest biome to the dimension
