Why is the "preview" blank? After writing the wrong code? Why in some cases I see correction and in other I don't?

After trying over and over to get my code right in this challenge, I kept on failing, So the first thing I did was as usual, going to the preview option to see where I got it wrong, but instead of seeing something to indicate where I was wrong, I saw a blank page. How come?

I'm stuck with that challenge and can't move forward. Please, what is the correct line of code for this challenge?

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
boolean invalidWord;
do {
   response = console.readLine("Do you understand do while loops?");
   invalidWord = (response.equalsIgnoreCase("no"));
   console.printf("Because you said Yes, you passed the test!");
} while (invalidWord);

This is the code the challenge is asking for:

// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
do{
  response = console.readLine("Do you understand do while loops?  ");
}while(response.equalsIgnoreCase("no"));
console.printf("Because you said %s, you passed the test!", response);  //this will only run if the user types in a response that is NOT: "no", "NO", "No", or "nO".

If you would like more detail on the do while loop. You can check here, on another one of my forum posts about the exact same code challenge: https://teamtreehouse.com/community/im-learning-java-and-i-still-dont-understand-the-purpose-of-using-a-boolean-variable-while-using-a-do-while-loop
