The certificates for the latest courses that I have set up in Moodle are not saving or loading properly. Two courses are affected. My uploaded border images display in the list when updating the certificate, but when I select and save, it reverts to the first border image in the dropdown list rather than the correct one for each course. The border image files are the same size, file type and format as all others uploaded to our Moodle certificates directory, and I can't isolate the issue. Please help!
