NIS 15.5.0.127 change my network security settings without my permission!!!

This morning I received the update 15.5.0.127, and my network settings have been changed without my consent. The security suite put in "shared" my wifi network, that I had in "restricted". This is a tremendous fail that affects my safety, since most people live and do not want any connection possibility between computers. When I look this mistake, I went to adjust  the network in "restricted" and reboot. But I was unpleasantly surprised when I saw that NIS returned it to "shared" network breach my orders.
If I make it clear that's happening would be very grateful to them because for me this is a very serious matter.
