Empty item group linked to invoices

Hey,

I had created a item-group structure then created some invoices with items that were on a specific item-group. I have since changed the item’s group to something else, but I can’t remove the old item-group which is now unused. It is in some way still linked to the invoices.

Either this is a bug or I am not seeing the logic in this. I have attached a few screenshots.

I hope someone can help me with this issue.

Sincerely,

Hi There,

I am having this same problem. I am trying to streamline the Item Group tree but since there are documents that have the items still referencing the old group, I cannot remove it. Is there a way around this?

This is despite all items update to their new group.
