SAME INVOICE NUMBER USED ON RETAINER AND "REGULAR" INVOICE

I created a retainer invoice on 5/8/25, #1427 and it took a few weeks for the client to pay the invoice. It was submitted to the client so it was “LIVE”. In the mean time I created a DRAFT invoice on another project and the SAME invoice number was used. That invoice was created this week sometime so WAY after the retainer invoice with the same number was created. This caused me not to be able to apply the client payment to the retainer invoice until I deleted the draft invoice. Your system should NOT allow for the use of the same invoice number.
