ZOHO Project Gantt Chart, viewing other User's Task?

ZOHO Project Gantt Chart, viewing other User's Task?

Hi all,

I can't seem to be able to view other Owner's task in the Gantt Chart for the specific project? I am the manager of the project and I've added Employee in the project and assigned task to them, but when I view the Gantt Chart I can only see projects which are mine and unable to see other Owner's task? 

I've tried the filter but there's no filter for Owner? 

Thank you
