Changing the payment date doesn't just change the payment date.  (Depending on the timing it can skip a month and charge you 'double' or can be less)

Check future bills - they should be at the expected amount.

You can't usually change your payment date until 2 payment cycles have completed.  Or perhaps this is a higher bill due to monthly in-advance charges?

Also, 31st is not an option - only 1st to 28th.  (To accommodate all months)
