Categories order in 'new topic' is different from /categories

I noticed that the order of categories in the ‘new topic’ window is different from the /categories page:


Is that a bug, or is there a setting I misssed that can change the order in the ‘new topic’ window?

Ordered by total number of topics in the new topic dialog, ordered by most recent topic in categories — not a bug, that is the way it works.
