Why do draft invoices follow different numbering than what is set in Settings?

As of now, BQE CORE has a fixed numbering scheme for draft invoices, which has the format: Draft-<number>. However, when you finalize the draft invoices, their invoice number changes according to what is set in Settings > Billing & Invoices > Invoice Settings or the invoice numbering scheme set at the project level. Check CORE Help Center for details.
