Buying at no cost aka material donations

I was wondering if anyone else is using ERPNext for non-profit work and could give me some insight into a problem I may or may not be having. I have a local instance of ERPNext 7 and would like to use it to manage donated materials coming in and the refurbishment (manufacturing) as well as the final delivery to customer. I can receive donations at zero price have them in inventory. However, I can close the buying ticket but it will always raise something needs to be done with suppliers but I cannot find any task to complete to make this go away. Any tips or mistakes I can correct?

Where do you get stuck, can you share some screenshots or more step by step details?

I think I was impatient. It clears after a little bit of time.
