Using only filtered elements in the excel download

[NayanaBhagat]

I have used activeadmin-axslx for excel download in active admin rails 4.
When I use the filters to fetch only few records based on some condition and try to download the excel with this fetched data, the excel shows all the data irrespective of the filters.

I only need that data in the excel that I have filtered.

Can any body help me achieve this?

Thanks in advance!
