Goods movement inconsistent status in Outbound Delivery

Hi SAP SD Experts,

I have one outbound delivery and its PGI was done.  However, the GI material document was archived (thought I did not know why or who did that). The status of Goods Movement is still shown as Completed and I cannot reverse the PGI.

Here is the screenshots for your reference.  I would be grateful if you can advise me solutions to sort it out.

Thanks in advance,

Regards,

Danny
