Synced account showing wrong balance direction

I'm trying to sync my mortgage loan account from my bank, and associate it with the asset entry in Quicken. When I sync the account as a "Banking" type, the balance is negative (correct, since it's a loan that I owe), but I cannot associate the asset with it. When I sync it as a "Loan" type, the balance is positive (incorrect), and I can associate it with the asset, but it is marked as paid off. How do I get Quicken to realize it's a loan and should be applied as a loan, with a corresponding negative balance showing? The value is correct, it's simply in the wrong direction.
