If you selected to delete items to trash instead deleting them directly (just in case you'd deleted in error), this does not work any more with Ubuntu 18.10 or Debian testing. Items are in all cases deleted, not moved to trash as with Ubuntu 18.04 before. Since this bug popped up with debian testing too, I'd thing it has to do with changes behind the scene and how trash is handled. Maybe dbus?
