Can't change NIC address?

I went into the network connection in the GUI desktop and change my NIC to manual IP but it does not stick on reboot. This if or Tricia V 19 I guess.

eg.
Code:firewall(/etc/NetworkManager/system-connections): cat Eth2*
[connection]
id=Eth2 - Local Network
uuid=55baf3de-14e5-3937-aa71-359d257528fe

[ipv4]

method=manual

[ipv6]
addr-gen-mode=stable-privacy
dns-search=
ip6-privacy=0
method=autoyet, still getting .160 from DHCP:
