Aqua Affinity, Flame, Silk Touch, Infinity, Channeling, Mending, and Multishot all display with I after their name as if they have another level, when in reality they are single-level enchantments. This is a very bothersome bug, as for the longest time I thought that Aqua Affinity had multiple levels, but it does not.

Edit: The resource pack I am playing with is of my own creation and does nothing to alter the names of enchantments.
