Help fixing Incorrect Leaf hardness!! (1.19)

So I attempted to make a custom Leaves Block, everything works, except that the hardness, no matter what I do decides to stay at the same hardness as a grass block instead of any leaves. Why cant I change it?

My full ModBlocks file (Leaf is LEAVES_ROWAN)
