Name Change

So my name change has gone through at the university. Perhaps I shouldn't have agreed though, when the administrative assistant who grabbed my form checked "so you're only changing your last name". Despite me providing a copy of the marriage certificate as proof of name change, I am still listed in the computer system with the courtesy title of "Miss". (And yes, I had to choose a courtesy title. The only way I can think of in which this isn't ludicrous is if I accidentally checked off the wrong courtesy title. In which case it is funnier, but not to me).
