I can see the importance of having a report that shows an active product bundle, Ian.
In QuickBooks Online, showing a product bundle that have been sold on a report isn't available and will only provide the information of the component items. You can run the Sales by Product/Service Detail report so it would show the quantity of each items and be able to track the items sold.
As a workaround, you can export the report instead and add the bundle on an Excel file.
Furthermore, learn how to filter some information when running reports. You'll want to customise them to make sure you'll have the information you need most. I've got this article for more information: Customise Reports In QuickBooks Online.
