Issue with task assignment of MNIs

Hi All, I'm developing a process (user satisfaction survey) that distribute task to multiple user.Each user had to fill and submit the task. I already check the "one-to-one assignment of task instances to assignees" on the Assignment tab and "Run one instance for each assignee " on the Other tab.

Everything works well until one user input the task. If user AAA fill the second form,or third form, that form will immediately send to other assignee in the user group eventhough the other assignee hasnt open the task.
Anyone know how to solve this case?
Thanks!!...
