USCIS FOIA Request for I-140 information (Sample G-639)

Hi All, My FOIA status shows “In Progress” when I use this link https://first.uscis.gov/#/check-status. But when I login to my FOIA account it shows as “Completed”, but there are no documents in “Document Library” section (except Acknowledgement letter). Did anyone experience this issue? If yes, what does this discrepancy mean and when did you receive the documents you requested for?

Please let me know if you need more details to address this concern. TIA.
