We have checked the online descriptes for the extended selection on s2survey.net, and did not observe any irregularities.
If you have double-checked your criteria for valid cases, and checked that the data appears in the "collected data" -> "view data", we can create an administrator login and check the question in your survey project. To do so, we need an email to info@soscisurvey.de, allowing us to log in to your project, the URL of the questionnaire, and the ID of the question, please.
