Enchants don't stop working.

### Describe the bug
A clear and concise description of what the bug is.

So I have my settings for the bow on the following:
infinity: 0
power: 0
unbreaking: 0
flame: 0
punch: 0

Most of the times it work but at some time it doesn't and then I get for example flame 1 on my bow. but most of the time curse of vanishing.

Also whenever update_inventory: true it doesn't update.

### How to reproduce the bug ?
1. Get around 7 bows.
2. Enchant them level 30, u see most of them are only curse of vanishing.
3. U see that it is not 100% accurate
