L1B伦敦签被check，但是当天CEAC显示Refused

你这个应该是真 refuse了，之前一波的状态(ap) 是这样的：

A U.S. consular officer has adjudicated and refused your visa application. Please follow any instructions provided by the consular officer. If you were informed by the consular officer that your case was refused for administrative processing, your case will remain refused while undergoing such processing. You will receive another adjudication once such processing is complete. Please be advised that the processing time varies and that you will be contacted if additional information is needed. For more information, please visit TRAVEL.STATE.GOV or the website for the Embassy or Consulate at which you made your visa application.

北京1.8号签，一直ap。今天变成refused+1。

我也是伦敦递签，之前都是AP，现在也是refused。但是昨天让我寄护照（check通过了），不过还是显示refused，应该是系统故障吧。
