Assessment Issue in Storyline360

Hi,

I'm working on an eLearning with a final assessment. Two of the questions I created are "Multiple Response" graded questions where the learner is supposed to choose three correct answers and the system is supposed display a trap message if the learner did not choose three answers . The Assessment works well the first time you complete the assessment but if you try to retake the same assessment a second time, the Multiple Response questions keeps showing the trap message even though I already chose three options. (Attached is a copy of the Assessment scene for your reference)
