I have a Citibank checking account and a line-of-credit attached to that account. Out of the blue, for the last month or two, transactions for my checking account are also downloaded (incorrectly) to the checking line of credit ("checking+", they call it). This worked correctly for years and nothing changed. But now, every time I download new transactions into my checking account, duplicates of these transactions are also downloaded into checking+ and I have to delete them.
What is going wrong here? Is it a bug on the Quicken side or the Citibank side? I changed nothing and it used to work, so it's not user error.
