Rsync verification errors after Discourse image cleanup

Hi. I’ve built up a very big pile of Discourse images, and decided today to run “launcher cleanup” in /var/discourse. No problems, got back a bunch of space, everything running fine afterwards. But now when rsync does my usual backups I’m getting “verification” errors with a “if you need to delete this raise an issue!” names on the files (see below). Any clues on how to resolve this? Thanks!
