OPT申请，Appeal Was Approved是什么意思？

本人11月27日收到确认邮件，今天查状态突然变成了Appeal Was Approved

The appellate authority approved your appeal and mailed you a decision. Your case, Receipt Number YSC189005XXXX, is being transferred back to the originating office for completion. If you do not hear from the originating office by February 24, 2018, please call Customer Service at 1-800-375-5283. If you move, go to www.uscis.gov/addresschange to give us your new mailing address.

然而我并没有去申诉什么东西啊，为什么状态会变成这样了呢，有没有前辈遇到过这种事情？

USCIS 那个傻逼外包网站的 数据库 sync又出错了。前天版里有个name was updated的。你翻翻贴。

打电话过去说网页显示错误。。。。
