Dressing check boxes

[pr0nsax]

I can't uncheck the Female NPC and the Male NPC checkboxes in the Dressing Options, is it supposed to like that?

I'm trying to get a male NPC to keep on a slof's boner, but he wont (and yes, I did set undress male to "never").

I'm having the same problem and can't figure it out for the life of me.
