I tried to use generate data features on my study, which includes a CBC study. Although the total number of respondent is set to 1000 by myself, when I get CBC results, I only see 27 respondents answering CBC questions. I double check the question script and csv. output file. CBC is asked for all 1000 respondents, however answered by only 27. I changed the 1000 respondent size to 100, and the number of respondents (27) doesn't change.
