Hi Simone,
Actually, the issue is not with the logic or the question type. Infact, it is the nature of the question because of which you seeing different results. A Multiple Response question is similar to a Multiple Choice question, except that instead of being required to make one (and only one) choice, the user is allowed to make none, one, or more than one choice. Whereas a multiple choice question can take only one response as an answer.
This is the reason you are experiencing different responses with both question types. I suggest you to please use ‘multiple choice question’ for this logic to happen in a correct way.
Kind Regards,
Kriti Sharma
