60033 was put in by Manager because some old invoice numbers had been manually modified by us. For example the “2” was added to “MIS6003-LC2”. When that was done the auto numbering changed. 60033 was later changed to a correct sequence but because we added the “2”, Manager kept putting 60033 for each new invoice.
What I don’t know is why we added the “2” to an old invoice number. It doesn’t matter now because everything is working properly,
