Samsung KNOX is not working
Once you flash your phone with ODIN then your KNOX flag will ALWAYS be triggered. Even if you flash an official ROM/firmware package. As you can see in download mode: KNOX WARRANTY VOID: 1. That can never, yes I say NEVER be reset back to '0'. So you haven't got any warranty anymore on your phone and you can never use Knox anymore.  Hope my answer helped you to understand the issue.
