[Forge/Bug?]ResourcePacks are not Able to Override modded Lang

Code:

    @EventHandler
    public void preInit(FMLPreInitializationEvent event)
    {
    	Item i = new Item();
    	i.setRegistryName("aa:b");
    	i.setUnlocalizedName("aa.b");
    	ForgeRegistries.ITEMS.register(i);
    }

Mod Lang:
C:\Users\jredfox\Documents\MDK\1.12.2\src\main\resources\assets\a\lang\en_us.lang

Resource Pack Lang:
C:\Users\jredfox\Documents\MDK\1.12.2\run\resourcepacks\New folder\assets\minecraft\lang\en_us.lang

Also tried:
C:\Users\jredfox\Documents\MDK\1.12.2\run\resourcepacks\New folder\assets\a\lang\en_us.lang

RP Lang:
item.aa.b.name=Z
tile.stone.stone.name=22

Mod Lang:
item.aa.b.name=Test

Display even on rp reload displays "Test" not "Z" like it's suppose to. Environment is fresh mdk forge recommended. I know the lang of the resource pack was working because, I overriden the stone block and it was working for vanilla

is this a bug should I report this?
