Workflow Roles Issue

System

I am having an issue in workflow setup.
The workflow that I have created, creates a new task when you assign a file.
The task gets assigned to a user called devmanager. This user has both admin and editor roles.
When I log on as admin I am able to change the status of the task.
When I log on as editor the task options show NA.
The same happens for author roles as well. (Not able to approve or reject)

I checked available_templates and I have not set any role_list.

The same wft file and available_templates work on a different machine for editor and admin.

Please suggest
