collection page issues on google chrome - ella theme

[angelsalumi]

website: https://www.angelsalumi.com/

For any collection page where people must click "show more" button at the bottom, the page will show products multiple times. On some pages the customer can never reach the end of the page that says "no more products"

Our shop uses the Ella theme 6.5.0

How can i fix it so the products will not repeat multiple times and customers can reach the end of the collection. 

This issue only occurs when using google chrome on a desktop. (other browers/mobile works fine)
