Hyrule Warrior's Link not working properly

[LKR000]

This is a bit of a strange one but every time I add one of the Hyrule Warrior's links from the vault to my sd card and load up the game, his textures on his shoulder plate and scarf are really blocky and pixalated. I've tried all of the many ones uploaded to the vault and they all have the same problem.
I use project m with a 4gb sd card if that makes  any difference which I wouldn't of thought so, so any help would be appreciated!
