Multiple date fields not working

[itmunky]

When using the date field option -f | --date-field, i can get a single date field to work however when using multiple fields as explained
"To set multiple fields to be tried in order until a valid date is found, just join them with spaces in a quoted string like "CreateDate FileModifyDate".
it just copies the photos into the unknown folder. It does not take into account either of the specified date fields.
