Changes made to a photo in Markup sometimes being lost when I export it on Mac
I made changes to a photo with Markup, then clicked done and then exported the file with File > Export > 'Export 1 photo', not 'Export Unmodified Original for 1 Photo.'
I then went into Finder, saw the file as a JPG, and double-clicked it. It opened the photo and showed it without the changes I'd made in Markup.
Puzzled, I restarted my computer, came in and did the same thing. This time I saw the export created a JPEG rather than JPG. I'm not why it would be different these two times, but this time the photo contained the changes from Markup.
Any idea what could have happened?
