Go into your options and select always show player name and you will see your own name and titles as they appear to others (I assume).
I noticed quite a while ago that every time I asked a trainer to let me pick a title, the already chosen stuff is black. Been that way for a long time. I just reselect, it's annoying but *shrug*.
I run with 'always show player name' on all my alts, I just like to see them. 🙂
