Yeah, that was a mistake that's now been corrected. Neither of those gentlemen are companions. We locked down "Companions of..." templates in July, and some changes had been made in the top half of the year that should have been reverted before locking down.

In other words, for years the wiki didn't consider them companions (Glitz wasn't even in the "companions of" categories), then a user snuck them in and we didn't notice their sudden inclusion in the navbox templates.

So that's a clerical error. Pay it no mind in the discussion of Courtney.
