After a team update, shared folders show root folders, why?

Since the update a few days ago from Dropbox, all shared folders's root folder and sub folders are now visible. Is there a way to revert back?

Here is an example:
I shared a folder called "folder 1" to my coworker.

 

Before the update, my coworker would only see "folder 1" inside his dropbox.

 

After the update, my coworker now see "root folder". In order to get to "folder 1", he would need to go through all my subfolder: "root folder/folder a/folder b/folder 1"

 

I don't want my coworker to see all those root folder and sub folders and go through all that hassle.
