请教一个错误选项的解释~ prep1-85

Jennifer789

In 1945, after a career as First Lady in which she shattered expectations more audaciously than either Abigail Adams or Dolly Madison ever had been, Eleanor Roosevelt was appointed a delegate to the United Nations General Assembly by President Harry S Truman.

解释中说 ever had been没有办法还原 所以错！
不太懂这里的不能还原的含义，是不是说要把 ever had been 改成did 与shattered对应呢？
可是AAorDM是发生在she shattered之前的，为什么不能用过去完成呢？思维混乱了 请教 谢谢~~~~~~

我是这么理解的，more...than 前后应该是对等的，但是ever had been是被动语态，但是SHE SHATTERED是主动，HAD BEEN后面明显是省略了（重复的）动词，那么如果是SHATTERED，说不通啊，应该是主动语态才是。这个就造成无法还原了。
