Shield and Shields listed for armor.

[MythicalRollers]

When you add an armor proficiency, there are two options for Shield. There is "Shields" and then "Shield".
"Shields" works and adds the proficiency correctly.
"Shield" sort of works, in that it adds a custom proficiency.

Oh I was under the impression Shields was a generic category like Light Armor, hmm I'll need to check where I'm getting that value from, thanks for the report!

I updated my comment. "Shields" works. "Shield" does not.
