I have no issues with it defaulting, but certain fields are showing blank under the item group.
The member items are populating fine, but qty, amount, tax codes etc aren't pulling through on those lines and I was looking for the CSV upload to provide the detail.
We are looking to have the option of producing invoices which can be displayed unbundled or bundled (using the display components on item group setup).
We also have different VAT considerations for different elements of the "bundle" and it is easier to manage as an item group vs kit.
