Ordering Enchanted Item Through /give Always Gives an Item with "Protection enchantment.level 0."

When ordering a diamond sword with enchantment ID 16 (Sharpness) through commands, the result was a diamond sword with a tag "Protection enchantment.level.0". I am confident that I used the command correctly, but just in case, here's what i wrote:

/give nbairen 276 1 0 {ench:[0:{id:16;lvl:5}]}

It should have worked, but if I did something wrong, please tell me. Otherwise, it'd be great if you could help, thanks!
