Why it keep showing warning message

Hi!
I just installed the wp and networks, when I login to the network control dashboard, it keep saying :

"define( 'AUTH_KEY', '7oqCBZI7W/{@;/$^/qg9Hw>OZ{!3+jIqc}k4@dPGx@?;,mw-<*Z^DstW=.xIBpL&' );
define( 'SECURE_AUTH_KEY', '6VTp7l`u+QMa}n,X[o5qR#+JEJd{]hgh(w@ByOqeKQFhnCZEs=E]FWLALI@V|Q$6' );"

But I already do as it told me to in wp-config.php, why ?
