All data in tabular sections disappeared

All data in tabular sections disappeared

Hello,

After doing a full export (all data, including the data in tabular sections) of the employee form I have done an import so I can re-map some fields, thus updating only the fields I was interested in. I can see now that somehow all of my tabular sections are empty. I don't see any reason why things are the way they are now.

Could you explain what happened? Is it a delay in refreshing my data? Can it be restored? I do have all the spreadsheets but can't seem to find a way around to import data in these tabular sections.

Thanks,
Raz
