You must have forgotten about it, but your bank records showed that you had made a deposit on April 10th, two days after the deposit you are referencing on April 8th. That's why it still wasn't letting you delete. Now that it has been three days since the 10th, it finally allowed you to delete. Just wanted to clarify this for any game staff that may later read it, so they don't think there's a bug.
Have a good day!
