I'm trying to blacklist an item from the mod called deeper and darker and Even though it's blacklisted, it still shows in jei and I can still spawn it in. did i do it correctly?
item_obliterator.json

Not sure if I trust that link. No offence

Having the same issue here with the exact same item.

is this correct?
