Notification by Project

I try to use notification by project and we have all theprojects like subfolders. I set notification on parent folder butwhen I check the subfolders there is no settings regardingnotification. In the Administration Guide on page 249:

"In the Notifications by Project tab, you add new statenotifications by selecting a file vault folder
where files are stored that should trigger the notification, thenselect a user or group that should receive
the notification.All subfolders to the selected folderwill be assigned the same notification unless
specifically set."

So this kind of notifications does not working.
I miss something or is a bug of PDMWE?
