SyncBackPro Doesn't Recognize File Hash on FileZilla Server

Greetings,

It appears to me that SyncBackPro is not recognizing the file hash feature that is available on my FileZilla FTP server.

Please see the two attached screen captures:

1) The SyncBackPro FTP Test settings, and

2) The FileZilla FTP Server log showing the file hash is available.

Is this a bug?
