QB Issue Resolution:
This happens because QB keeps a ‘high water’ mark and once you import newer transactions it is assumed that the older ones have already been import / should be ignored.
To import the older transactions anyway, edit the bank account on your chart of accounts and remove the online banking/bank feeds setup from the account. Then import the oldest of the QBO files first and then each subsequent one.
