If this CK works the way the ones for Fallout 3 and New Vegas did, it's because you have nvde mods installed. The CK will display the game in the render window based on any mods you have installed, including those.
HAHAHA,as if I'd install nvde mods.
Will try the outfit thing, Eisoj5.
EDIT: Thanks, it was because they weren't in an outfit. My bad, I was expecting inventories to work the same as they always have.
