You cannot assign the same task to different individuals (actors). That would lead to concurrency problems like both persons starting the same task. Whose actions are really driving the task? You need a way for your users to see a group task list where they can take ownership of the task, or a supervisor/manager can assign it to them. The bottom line is that you can have only one single actor can be assigned to a task, or a group as you have found out. At least this is my understanding of it.
