Meaning of different icons for sync folders not downloading

I have set up the Mac Client sync v3.1.2 but discovered that the folders (marked with grey-out lines) has a different icon and could not be sync’d to my desktop locally. What is the meaning of these directories with different icons from a regular Folder icon?

I realize these are all folders shared by others with me. However, I am trying to sync everything locally, including those folders that are shared with me.

I do have admin permission and have added myself to allow sharing on these folders. However it still fails to allow me to sync those folders. What are the steps I need to work with IT team to let me sync all the folders to my local machine?
