When automatic credit card payments (set up through the credit card companies, not through Quicken bill pay) are downloaded, the category in my checking account register shows up as a transfer to the same checking account (in brackets), and the payment shows up in the credit card account register as a transfer to the same credit card account—so that it's not obvious which checking account (I have several) the payment came from, though the balances are correct in both accounts. If I then manually change the category in either the checking account or the credit card account to cross-reference the other account, it duplicates the transaction in the other account, and then I have to delete the downloaded transaction in the other account.
