clearing an item from an advancement reward function doesn't remove it

I have a custom advancement that detects if the player has a knowledge book with a specific

recipe (using the inventory_changed criteria)

"criteria": {
"book": {
"trigger": "minecraft:inventory_changed",
"conditions": {
"items": [

{ "item": "minecraft:knowledge_book", "nbt": "

{Recipes:[\"minecraft:bow\"]}

"
}
]
}
}
},

this advancement triggers a function 

"rewards":

{ "function": "aaa:got_bow_recipe" }

,

and inside the function are the following 2 commands:

recipe give @s minecraft:bow
clear @s minecraft:knowledge_book{Recipes:["minecraft:bow"]}

despite running a clear command, the item doesn't leave the players inventory, but also doesn't exist, until the player updates their inventory

Running the command /data get entity @s SelectedItem says that there's no selected item

Running a general /data get entity @s also says that the item isn't in the inventory
