权限更改不一致

我为文档库中的一个文件夹切断了父级权限，以便为这个特定文件夹自定义它们。

I severed parental permissions for one folder in a document library to customize them for this specific folder.

一切顺利，除了一个人现在看不到该文件夹在图书馆中，而同一权限组中的其他人也这样做。  

It went well, except one person now doesn't see the folder in the Library while others in the same permissions group do.  

他的配置中的所有内容都相同。   我找不到任何理由。 我最终与他分享了这个文件夹作为个人，他可以访问它。

Everything is identical in his configuration.   I'm not finding any reason.  I've ended up sharing the folder with him as an individual and he can access it.

有没有想过为什么这个人丢失了整个文件夹？   我可以看到类似"您无权访问此文件夹"的内容但不是完全删除文件夹！

Any thoughts why this one person lost the whole folder?   I could see something like "You don't have permission to access this folder" but not removing the folder completely!

谢谢。
