I have just reuploaded the files again. At some point during the processing, the files are not being recognised. The system seems to recognise the file name. I see the file size, I can click on the files and their content shows. Now I see they are not showing. From the diff Revision as of 19:47, 29 August 2020 by Owaine1, seems to show the 4 files, 1 in scores, 3 in librettos. And those do not show up as blank as of today, and they were not blank either yesterday. So I just do not know.
Unfortunately it's still not right. I tried downloading the files, and they open fine in my pdf viewer, but then when I tried re-uploading one of them, the same problem occurs.
