申請延期 但收到ETS令人困惑的回信 - 英檢

本來我報了本週六4/23的考試，但因為某些因素決定延期到7/23。
上週一在線上完成延期和繳費手續，
但週四時收到這封ETS的信：

Dear XXXXXX:

We are writing to inform you that the TOEFL iBT registration you were
to reschedule for July 23, 2011 failed to complete on our database due to a
processing error.

When one registers successfully, a 16-digit registration number will appear
on his/her file and assure that a seat at the test center is reserved. In your
case a registration number was never created. Nevertheless, we were able
to register you again for the same date and test center, free of charge.

Please refer to your web TOEFL profile to reprint your admission ticket.
Copied below is your appointment information which we have also emailed to you.

但我剛剛登入系統發現系統上有顯示我7/23考試的Rigistration Number
然後有兩筆Old Registration information，
最下面是本來4/23的完整資料，
上面接著一筆改期到7/23卻沒有rigistration number的資料，

看起來似乎是系統自己忽然想起來了？
這樣我還需要重新modify嗎？
有哪位先進延期時遇過這個狀況嗎？整個讓人一頭霧水阿！！！
