Lockpicking Enchantments

I have found there is an echantment named “Lockpicking” wich gives you Lockpicking and Alchemy, it costs 7, and there is another named “Fortify Lockpicking” wich costs 7 and only adds Lockpicking, both are armor enchantments.
It seems just a typo, but they have different names and images, should it be totally different?

Nope. They are the same. The Alchemy symbol is a typo.
