The thief tab shows unbreaking 1 no matter what enchantment it actually is. For example prot 4 mending 1 armor shows as Unbreaking 1 Unbreaking 1 armor.

Might be hypixel exclusive bug idk if it like handles enchants differently

What minigame? also moving this to https://github.com/Ruukas97/Infinity-Item-Editor since its for the 1.12 version

If this is still an issue create a new issue.
