How to scrape from a popup page that has same URL as the main page

How to scrape data that comes from a pop up page which has the same url as the menu url? my english is so bad so i'll try to explain it through pictures

that picture is the main menu in which i fill out a form to show only the data i needed

and this is the page which opens up in a new tab

i try to scrape the data from the pop up page, i've done the process just as the tutorial provided in this page, when i tried to view the data extracted, it work as intended, but when i scrape and export as csv, it show the result from the first page which is not the page that the data resided

this is the url that put in the sitemap url, both pages has the same URL
Url: http://103.151.227.36:8060/index.php/laporan/krsmhsparam
