问下两次DBdoctor出现结果不一样是什么原因啊？

我画完板子后进行DBDoctor时出现
ERROR IN ATTRIBUTE
  POINTER TO ATTRIBUTE INVALID
   Error was fixed.

没做任何修改，再次进行DBDoctor时出现
Number of Xnets before update: 0        after update: 0
Number of Diff Pairs before update: 10   after update: 10
没有出现第一次的WARNING，问下为什么会这样的啊?
谢谢各位啦~~~

已解决，原来是没更新
