HELP - No invoices showing up in invoices tab

[defaultgl2ym3btrgb6]

Hi, I purchased the extended licenses for about 15 images and I need to send the invoice receipts to our client to show proof of purchase. I have all individual emails that say the order number and to click to view the invoice, but when I open my invoice tab it is completely empty. This is ridiculous that not a single invoice is in there. I cannot send them 15 separate emails as proof of purchase. 

Please help.
