Credit Card Payments are typically considered as transfers from your bank account to your credit card account and are not accounted for in the Cash Flow. This is because, if your credit card is already linked in Empower Personal Dashboard, then the individual transactions under that account should be included in the 'Expense' section of the Cash Flow. Including the Credit Card Payment also in the Expense will double your credit card expenses.
It also can't be counted as a credit to your 'Credit Card account' because then the expenses the positive transfer will cancel each other, giving the impression that the total expense was 0, which is also not true.
