My requirement is to get extract output in .csv(not .txt file with comma delimiter)  file below options i tried unfortunately nothing is working

Option 1) setting extract output as a csv in delivery and template output format as  csv

it is generating csv file but not considering the template. all the fields in selection are printing in .csv file including parameters and other information.

Option 2) setting extract output as csv  in delivery and template output format as text

extract completing in error as output types are not matching
