Thanks for clarifying, @Batman69. I understand what you're going through about the downloaded transactions showing different descriptions in QuickBooks. 

Checking on our records, we don't receive any reports similar to what you experienced with Commonwealth Bank. At this point, I'd recommend contacting the QuickBooks Online Customer AU Support team. They can help check and identify the cause of the issue and open a case if it needs further investigation. 

Feel free to visit again if you have more concerns. I'm always around here to listen and help.
