Stanford Stats Master-Data Science Track申请网站跳出提交成绩链接

申请的是Stanford Stats Master-Data Science Track，上星期发邮件说decision delayed了，然后今天申请页面上跳出来一个 CertiFile (Certified Credentials Attachment Service)，
Certified credentials can be ordered from the school(s) below:
UNIVERSITY OF XXXXXXX
Using CertiFile is optional. For detailed requirements on submitting official credentials, please refer to your department/program.
最后还有一个Initiate CertiFile order的按钮。
求问还有小伙伴收到了吗？这个是现在需要提交吗，还是一个网站bug？
