Usually in Facebook Ads, the same creative could be present in multiple ad sets with multiple audiences. But in the report, you want to show the aggregate across ad name or image, instead of having the image appear multiple times.
Below is the procedure to achieve it ReportGarden.
Select '''Facebook Ads'' as Datasource
Choose the dimension as "Ad name"
You also have an option to display the ad instead of the ad name, in the advanced tab. You can choose to toggle it on and select the format that you want to show.
