Short answer: The label was most likely not cancelled before 23:59 on the day of creation.
Explanation: Please be aware that labels must be cancelled before 23:59 the same day as label creation, otherwise you will be charged for the label. However, If you miss the same day cancellation deadline, don't worry - you will be charged on your next invoice, but as long as you cancel the label within 42 days from label creation, the costs will be reimbursed on the following invoice.
