Hello. There is one specific question in my questionnaire, that remained empty in 5 out of ~200 respondents. When I say empty, I mean the field seems white, meaning "not asked or irrelevant to calculate MISSING". When I open the answered questionnaire from these respondents/cases, it seems as this particular question was never asked to these people. Is this a bug? What can I do to retrieve this information - assuming it can be found somewhere? I should note that I labeled this particular question as mandatory ("the question must be answered"), and all previous questions that had to be answered were answered properely. I thank you in advance
