Brown ds是提前了ddl吗

刚刚收到Brown招生官发来的这封邮件，官网上写的项目ddl是2.1，邮件上写的“Your application expires at the deadline for the program to which you are applying. If you have any questions, please reach out to masters_admissions@brown.edu to connect with an admissions representative.”
问一下大家，这个意思是ddl已经提前了不能申请了吗

不应该呀，我看也是2.1
