Rclone sync doesn’t delete empty folders

Hi,
I'm experiencing an issue where empty folders created, synced, and then deleted from the source are still left on the destination.
I'm using rclone with a crypted folder on a Swift backend.
After syncing files, any empty folders created during the sync process remain on the destination, even after the source is cleaned up.
Thanks
