Feedback in Rise - Correct/Incorrect without revealing answers

Hi - I've put together a course in Rise and passing (80%) of the Final Knowledge is mandatory.  I seem to be unable to adjust the settings of the Final Knowledge check to let the learner know their answer was correct/incorrect without providing the correct answer.   I've enabled multiple attempts to take the quiz  and it would be helpful to let the learner know if their answer was correct/incorrect without providing answers.   Thanks.
