My accounts are linked and have been since launch but I did not have this title then. I recently decided to go back and work towards getting it and I finally got it today. I cannot seem to get it to display in gw2. I have tried logging back in on the gw1 character with the title multiple times and then back into gw2. Is there something else that I need to do?
Thanks for submitting a ticket. I generally suggest that a playler wait 24 hours, because sometimes it takes time for things to “reset.” I also recommend fully logging out and logging back in, as well, but I assume you tried that… perhaps multiple times. 
In your discussion with Customer Support, an agent may ask for permission to access your account in order to review your title history. Don’t worry, that’s legitimate, and we will not ask for (or need) your password or other credentials. We also will not ever ask this in the game, so if someone asks, ignore!
I just wanted to mention that, rarely, we do need to access in order to see things from your viewpoint.
