I had this bug on an NPC I made, and fixed it using the procedure on the Dark Face Bug wiki page. However, I have it with a different actor. Whenever I highlight the actor and press Ctrl+F4, absolutely nothing happens-- the dialog window doesn't even appear. I waited for probably 5 minutes and nothing ever happened. I also tried restarting the CK and the same thing happened. I have verified that there's nothing wrong with my F keys. It appears that there is no other way to export this data so I am stuck with a grey faced actor.

Interestingly, "creation kit ctrl f4 doesn't work" and "creation kit ctrl f4 does nothing" are suggested by Google, but I haven't found a relevant result on either of those searches.
