I find the invoice numbers do not appear consistently within the Customer Report. I can't say when it started, because only in the last few years have I been using the Customer Reports consistently. It does not matter if the invoice number is external to Gnucash or is generated by Gnucash.
I've filed a bug Bug 799386 - Invoice numbers do not always appear on customer report and welcome anyone else using Customer Reports to add any information if they see the same behaviour.
