Blockstate based Loot Tables

So, I got the recipe down, making 4 armadillo scute craft an Armadillo Scute Block, which is a mud brick slab with the blockstates of type:double & waterlogged:true. 
I tried figuring out the loot table drop using Misode's Loot Table Generator and got confused with how the formatting works.
What I am going for is regular mud brick slabs and double slabs having their normal drops, but I want the waterlogged double variant to drop 4 armadillo scute.
Here's what I got from my attempt:
