Hi there, @jakmaartens.

I appreciate you for providing the phone number of our support and manually downloading the transactions into the system. This information will surely help other customers to call them directly. 

Manually importing data into the system will help you categorise and reconcile the account regularly. 

Just in case there will be duplicate transactions, you have an option to delete or exclude them. QuickBooks will stop the bank from bringing the transaction into the bank feed again. For more information, check out this link: Excluding VS. Deleting.
