Ajax loading of news does not work on a page with news.list components?

Question

1C-Bitrix

Hello. Tell me, please, on our page there are several bitrix.news.list components with ajax news loading, which we did ourselves. The first component works fine, i.e. loads the news as it should, but the second component behind it already works wrong, it just loads the same news that is already on the page.
By the way, if you leave one component on the page, then it works fine.

The ajax script was made according to this guide - mattweb.ru/item/98-zagruzka-novostej-s-pomoschu-aj...

Help, please, how can this be solved?
Thanks in advance.
