Version 4.7.3 Synchronizes remote folder to local folder on first attempt. Reload of current job in transfer window will sync again. After Cyberduck is restarted and the saved synch job is reloaded, or if a new synchronisation task pointed at same local and remote folders (with or without existing and restarting), cyberduck can't read file metadata and displays yellow exclamation mark on all files. If you click on a file at this stage, file info shows as "Unknown".

Version 4.5 does not exhibit this fault/behavior/feature. I've downgraded to get the job done. It looks like a bug.
