Pagination wrong sorting?

why pagination start from end page (20) not start from page 1 ?

it is a bug?

reference:

@3xploit Hi, no, it is not a bug. The scraper traverses pages in pseudo-random order, the order of records in the scraped data will not correspond to the order of start URLs for the sitemap and may change when new start URLs are added - unfortunately, it is currently not possible to change this behavior.
