The hooded version of the Mythic Dawn Robes (ClothesMythicDawnRobes) isn't uniquely named to differentiate it from the non-hooded variety. If you think it's a bug the name field could be changed to "Hooded Mythic Dawn Robes" instead.
Something else I noticed is that the inventory and world art are identical. Though I didn't look to be sure, there probably isn't a unique hooded mesh available in the game.
