I have a similar issue.  I have some deposit transactions flagged with the 'Partially matched' error, but I have no matched transactions and the message says 'Partially matched: $400.00 remaining out of $200.00'.  Why would the remaining be greater than the amount mentioned?????  I have tried numerous things to get this working, but can't seem to figure out why I'm getting the error.  Please note that I have 3 transactions for $200 on 3 different days, all of which show this error.
