Turning off Unauthenticated Identities in Amazon Cognito for IOS

I disabled access to Unauthenticated Identities and found that my Logging threw these messages:

Is it complaining about my CognitoRoleUnauth parameter defined in Constants.h? I have valid ARN supplied for CognitoRoleAuth, and valid CognitoPoolID and account. It has been working well with the unauthenticated Identity, but I must close that off now.
