Bug : behavior - export this view to a csv file

Hi, I’m unable to export csv file with a filteredview from a slice.
It generated blank csv file with only header.

  1. I got a form for user to fill in data for filter table. Saving on the form will go to a filtered table (slice) view.

Filtered Action

  1. It successfully dsiplayed the filtered data, but failed to generate csv file with the data.

But it only has column header in the csv file.

Please help.
