Posting Invoice stops with No. Series missing error

Hi, I am trying to post invoices for two shipped sales orders. The goods were manufactured from the same orders.

I am getting the following error:



The Series does not exist. Identification fields and values: Series='V-FAC'

I have checked and the series does exist and are configured in the Sales & Receivables Setup. See below images:





I've noticed that if I try to change the series, the numbering or anything in the Sales & Receivables Setup or the No. Series pages the sales order is still trying to find "V-FAC" and using the same Invoice No. 1033.



Your support is greatly appreciated.
