curse of blindness still show it's description as item name.

it can be fixed easilly.
in language file(en-us.json), there is two name value.
"enchantment.cursed.blindness": "Curse of Blindness",
"enchantment.cursed.blindness": "Drastically lowers the vision of the user.",

second "enchantment.cursed.blindness" missed ".desc".

so editing this to
"enchantment.cursed.blindness.desc": "Drastically lowers the vision of the user.",
will fix problem.

lang.zip

here is fixed files for 2.0.1

Thanks for reporting this issue. I fixed it for French and Chinese as well.
