In this survey, I have totally 576 questions. I duplicated a block over 20 times with the same questions. Most of the blocks will not be displayed to the subjects due to a randomizer.
However, on Data and Analysis page, I can not choose the columns to add the responses to my questions. Even I exported the survey data to .tsv, it only recorded Survey Metadata and Contact Fields. I still could not find the responses to my questions. The screen shot is like this.

Then I tried to delete some blocks and when there were 421 questions in the survey flow, I was able to choose the columns to add the corresponding responses again. The screen shot is like this.

I even tried to delete different blocks and found out that which block was deleted did not matter, but the number of blocks (maybe the number of questions) left in the survey flow did matter.
Could you tell me how to get the responses to my questions when I want to keep all the 576 questions. Thanks!
