It looks like some banks are no longer following the spec for QFX/OFX files. They are labeling all transactions as debits.
Moneydance has added a workaround. You need to be running the latest build of 2019. Make sure under FILE (MONEYDANCE on Mac) – PREFERENCES – NETWORK that IGNORE TRANSACTION TYPE IN FAVOR OF AMOUNT SIGN is ticked and see if that helps.
You don't indicate if you are running 2019 or purchased 2017 and thus entitled to a free upgrade to 2019 or are running a earlier version and would need to purchase 2019 at a 50% discount.
