All ore blocks are call block of ore (i.e Block of Coal, Block of Diamond, Block of Netherite.) Except for Lapis Lazuli which is called Lapis Lazuli Block instead of Block of Lapis Lazuli. This might not be a bug and might change between languages but it is like this in English (US). I think this should be changed because it makes sense for all of the ore blocks to be named the same way.
