"Invoices" have been changed to "Pledges" when I categorized us as a Nonprofit. We need invoices, and we are a Nonprofit. Why can't both be true?

This is super annoying. We're a Nonprofit, and we need to be able to invoice. We don't use "Pledges". When I accurately categorized us as a Nonprofit in our Company Info, everything changed to "Pledges". I need both (1) that we are a Nonprofit, and (2) that we have access to Invoicing, calling them Invoices, to be true. There is no reason for this not to be possible - come on, Quickbooks!
