'Try again' in MCQs

I know that you can ‘try again’ in branching scenarios but how do you do this in MCQs? I’ve set up an MCQ with multiple attempts but it doesn’t let the user try again.

Under the questions “Behaviour” settings just put in how many retake attempts you want to allow them. When they get it wrong, they should be able to click Reset where the Submit button was before, and try again. Is this not happening?
