Bought the wrong timeslot for express pass tickets for Universal Studio 😅

Me and my friends are going to Japan in a week and I was reading on reddit and other forums that you should get Universal Express Passes because of the 150min> wait times for certain rides. So I decided to go to universal's website and buy the Express Pass 4 for the Race and Thrills part of the park.

However, for some reason the website only lets you buy 4 tickets at a time and there are 5 of us going. So I decided to buy the first 4 at one timeslot but accidentally bought the 5th one in a timeslot that is half an hour earlier to the one that the other 4 are in. These tickets can't be refunded or sold.

Not sure what my options are 😭, should I buy another ticket for like $170AUD or would the staff at the express pass lanes be kind enough to let it slide.

Thanks in advance
