Item missing in Billing

Carl's Land Works

I have "items" set up for my customer billing that is associated with a category. However, on some bills, the "items" disappear, along with the quantity associated with the invoice, and all that remains is the "category" listing with the price associated to the item. This is not happening will all of the invoicing. Can anyone tell my why this is a thing? I've tried deleting the invoice and re-entering it, made sure all of my items are associated with a category, etc. The invoice "saves" correctly, with "—Form—" showing under the Category heading, but once I exit Quicken, upload my data to the cloud, and then go back in, the Items disappear. Again, not in ALL invoices, only in some. Thanks for any help you can provide.
