Export Underlying Data: Table Visual vs Chart Visual

Hi,

I am exporting underlying data for a table visual and a chart visual. They have slightly different fields but it comes from the same underlying table. The problem I have is that the table visual does not give me all the columns as compared to the chart visual. There are some measures in both visuals as well but the table does not export it.

Is this a known problem or is it designed this way?

Thanks!
