distractor analysis error

[Elvire Alice]

Hello,

My name is EA and I am working as a language test developer. I have recently taken my first steps in the world of test analysis and I am still learning about the wonderous world of Jamovi. We know that ideally a test should comprise of more than 10 items to do a proper analysis, but for now, this is what we have to work with. We have an issue with the distractor analysis of a particular test batch and even though the parallel test forms are equally comprised of 10 items, there haven't been any issues with the other analyses. We keep getting the 'breaks are not unique' error and although we tried to resolve the issue, we cannot find the problem. We have inserted the test takers' answers again in an excel file, changed it to csv, changed the language settings, etc. I am just a beginner so that is why I am reaching out to you. Maybe I have overlooked something? If you need extra info, please do ask. Thank you so much in advance for your time and effort.
