FTP-Backup

Tried comodo Backup at version 1.0.1.10 by coosing an ftp-server for my backup destination.

comodo Backup allways tries to enter the ftp-server in passive mode altough I unchecked the checkbox in settings for passive mode.

Is there a bug? Or am I wrong with this behaviour, and didn’t find a workarround.

fyi: passive mode is a better default, as it only requires the control of port 21.
