Hey Confusedas, that sounds unusual. You can try exporting all your transactions from the reports list (found in settings), and download them to your computer. This way you can confirm all the receipts that you have uploaded using the mobile app.
If you needed more specific advice to your company, try reaching out to the support team. You can do this by speaking to the assistant (in app), and ask to speak to a human. Alternatively, you can message the team here: https://help.quickbooks.intuit.com/en_AU/contact .
I hope this helps!
