The bug:

The enchanted book can be enchanted again after enchanting when I try to enchant a book with the enchantment value of 64.

Steps to reproduce:

1. Give yourself any item with the enchantable component and the stored_enchantments component.

   /give @s arrow[enchantable={value:1},stored_enchantments={levels:{protection:3}}]
   

2. Enchant it in a enchanting table.

or

1. Give a book with any enchantment value greater than 1.

   /give @s book[enchantable={value:2}]
   

2. Enchant it in a enchanting table twice.

Observed Behavior:

The enchanting button is highlighted.

Expected Behavior:

None of the buttons are highlighted so you can't enchant the item.
