Extra folders showing up in Network that i not shared

Im sharing 1 folder called Media on the network. When I try to access the computer to see the shared folder on another computer i see other folders shared which i didn't share.

Now since trying to fix this, My Android phone cannot access Music, Pictures, Videos folders located inside the Media folder. Other folders it can access fine, Documents, Downloads etc. Why is this.

Ok i fixed it by going into network folder on the pc sharing the folders and just unsharing them. Did display an error, but just ignored it.

And to fix access to the certain folder for the android. I right addedd security permissions to everyone read access in the "Libarays"
