This seems to be a new bug (even though the result seemed the same), so I'll create a new issue.
Via email, the jury coordinator mentions:
"I didn’t stop the round and then create a new one. I just set it once. The night I created the round, everything seemed ok; the photos to be reviewed were 560(ish), but the next day, when I opened Montage, they were 1054."
