"Looks like you didn't censor words" but works in IntelliJ?

So, my code compiles and runs as described in the TODO's, but when submitted via the Treehouse Challenge, a Bummer message appears claiming the censoring doesn't work when in fact it's tested and working through IntelliJ.

#  This is essentially what I am testing 
1.  The user is prompted for a new string template (the one with the double underscores in it).

  a. The prompter class has a new method that prompts for the story template, and that method is called.

2.  The user is then prompted for each word that has been double underscored.

   a. The answer is checked to see if it is contained in the censored words.
      User is continually prompted until they enter a valid word

3.  The user is presented with the completed story

I figured it out. I had to remove the if() statement that contained the System.out.printf(); command to alert the user their word was censored from the promptForWord(); method. Here's the revised method:

public String promptForWord(String phrase) throws IOException {
        String word;
        do {
            System.out.printf("Give me a %s:  ",
                    phrase);
            word = mReader.readLine();
        } while (mCensoredWords.contains(word));

        return word;
    }
