Auto Invoice error : You must supply an invoice number when your batch source indicates manual invoi

Hi,

I run auto invoice and get this error 'You must supply an invoice number when your batch source indicates manual invoice numbering; otherwise you must leave invoice number blank'

In this case I'm auto invoice from 3 sale orders, same delivery number, there should created in one invoice or difference invoices?

Now, 1 of 3 has invoice created but 2 of 3 are stuck in interface line with error 'You must supply an invoice number when your batch source indicates manual invoice numbering; otherwise you must leave invoice number blank'.

Thanks.
