My new Perk Deck mod isn't showing up in-game

Hi there, I'm currently working on a perk deck (mostly as a test) but for some reason, the game loads the mod but the perk deck cannot be found in the list. It's probably a minor error, but I can't find it. Any help?
Here's the deck: https://www.dropbox.com/s/o02ifxvx759urtb/Custom Perk Deck.zip?dl=0
