We have 10 unit in our course and for each unit we have selected 'User needs to answer all mandatory assessments and view all pages in order to access the next unit'. This working except that in unit two there are 12 mandatory questions, but when all questions are answered the course progress page says '12 of 13 mandatory items completed'. This prevents the student from progressing to the next unit.
There are only 12 questions. In the student assessment it correctly shows that 12 questions have been answered. How do I find and remove this 'phantom' 13th answer field?
