Invoice Export as PDF-P.O goes missing

Invoice Export as PDF-P.O goes missing

Hello,

I noticed since yesterday that the export as PDF function under invoice functions has an issue. The PO number which I input on the webpage is not shown in the PDF format. All I see in the empty P.O row is "P.O.#".

Developers please fix this asap as I don't want to end up filling P.O numbers by hand in each invoice.

Thanks.
