Can u please delete the data source of the Group inside repeating group. Or both the data type and data source. Then change the text elements text to current cell’s options display. Just to check whether group inside the repeating group is not blocking anything.
Try both using or not using the data source of the group inside the repeating group
You can also create blank page and create the repeating group there. And just create a text element inside the cell. And create text element’s data to current cell’s options display. Do not create any groups.
I often do this to find out the mistakes not only for repeating groups but for anything.
You need to go through the intro videos, and check YouTube videos. Then you will have a better idea of what to do.
Have you actually create any data in this option set?
