I used to be able to do a download of single submissions as a pdf, then recently the same process leads to a zip folder being downloaded of multiple copies of the same submission, or of an earlier submission and not the one that I had selected......frustrating

We are sorry about the difficulties you are facing. I was able to download single submission as PDF when testing. Could you please clarify if you are downloading the PDF via Submissions page?
