The Payment to the card provider is not Split into any expense categories; it is paying down the card account (debt) balance. You should have the credit card Type of account or category, for this reason. Your spending details are from the Card Provider. The Payment between checking and credit card is never office supplies or fuel or any other Expense reason; that is your debt balance payment. You would only Split that payment if you have more than one credit card account needing to have the payment allocated to them.
