This occurs because of how we process the files in the backup directory. At the moment, only files that are marked with the same date format provided in the DBBACKUP_DATE_FORMAT setting. It should technically be possible to add a setting or a command option to show the other files, but the date time field wouldn't be populated, making the management command a shortcut to list the documents in your backup directory.

The other option would logically be to apply the time format to the file name in some other way through the backup command, though we would need to make sure it's very deliberately applied and communicated with the user.
