unwanted folder showing up in network access, rn2120

 On a new 2120, I installed, updated and configured. 3 "users", 8 shares not including home folder. 1 of 7 folders is hidden. On the web interface all 7 and the home folder are visible. When accessed through our network, the shares are visible and a folder called "data" appears (the home folder also appears). In the data folder are the other shares, including the hidden share, all shaers open, including the hidden even though they are password protected. How do I hide or get rid of the "data" and home folder from appearing when accessed through the network?
