Filter is not working after export to csv

Hello Experts,

I have created a WEBI report on Universe Design Tool my requirement is to show last 7 days data. I created the formula and added in the filter. When i export it in csv format it shows all the data seems like the filter is not working. When i export it in other formats such as webi, pdf and excel format it shows the 7 days of data. Can anyone of you help me out to fix this issue?

I appreciate your help and time.

Thanks,

Shehzad
