Did you talk to The Lady in NQ who gives you the tradeskill title? I became a scholar at level 10, and my title showed up then. But you have to first craft any item, and your new title will appear. So if you already chose your title in NQ, try making something, and see if the title shows up for you. I just hit level 20, and I went thru the same thing. but as soon as I make something I then saw the title on my profile.....
