Issue in Fingerprint model

In this model: 

/SecureAuth.Sdk/Models/Fingerprint.cs for the call 

`service.DeviceFingerprint.ValidateDfp(new ValidateDfpRequest(txtInput.Text)
                {
                    UserId="joe",
                    HostAddress= "*.*.*.*"
                });`
User Agent shows as required, however neither the implementation nor the finger print from the js has that value.
