Do I need to do something further to confirm Adjustment?

I originally applied to do Law with Criminology at The University of Sheffield and put this as my firm choice which I was accepted on to on results day. However I went through Adjustment at the same university but for European and International Law instead. I applied lunchtime of results day and they phoned back at about 5pm. The person asked if I wanted time to think about it, but I accepted there and then. I then got an email through confirming that they had offered me a place and that I had accepted it. I had already registered for Adjustment on track by this point. Yesterday I received my accommodation contract through, but Track still says that I am doing the old course and that I'm in Adjustment. Any idea how much longer I should wait for it to update or should I ring UCAS? Only have until the 19th August for Adjustment!!
