Kindly please be informed that data from the repeat groups is not visible in the custom report nor is it visible in the view-table-data. It’s only visible while downloading the data in the xls format.
However, there is already a features request and maybe you could VOTE to make it a reality in the upcoming days:
Okay, but the problem is when we download a lot of data, I can’t watch the groups.
Just if we download a couple of data we can watch the groups. @Kal_Lam
Could you share with us a sample so that we could better understand your situation. Maybe a sample of your dataset in xls format. If you feel it should be treated confidentially, please feel free to share it through a private message.
