I have a multiple choice quiz with instant feedback turned on. When a user selects an answer it correctly puts either the green checkmark or red x next to their selection, however, the form does not bold the correct answer. Instead it always bolds an answer to the first question.
For example if the correct answer to the second question was the first answer it might bold the first answer to the first question.
Not sure if it's relevant or not but I also have the default Gravity Forms CSS turned off and randomized answers for all of my questions.
