Spawn.json can't get skeletons to have different weapons on spawn.

[CdysRed]

I was hoping to make skeletons have more variety of weapons than bow on spawn, as well as a 1% chance to have full modded bone armor with extra health. Does not happen.
This is what my spawn.json looks like:
[
{
"mob": ["minecraft:skeleton"],
"when": "finallize",
"result": "default",
"helditem": ["5=wrd:bone_sword", "1=minecraft:iron_sword", "1=minecraft:bow", "1=iceandfire:copper_axe", "1=iceandfire:copper_sword", "3=wrd:bone_crusher"]
},
{
"mob": ["minecraft:skeleton"],
"random": "0.01",
"when": "finallize",
"result": "default",
"healthmultiply": 1.5,
"armorhelmet": ["immersive_armors:bone_helmet"],
"armorchest": ["immersive_armors:bone_chestplate"],
"armorlegs": ["immersive_armors:bone_leggings"],
"armorboots": ["immersive_armors:bone_boots"]
}
]
