When the button is clicked in the drop-down menu it shows that the page cannot be found

On the wordpress website, because the background cache of woocommerce is cleared, some products display that the web page cannot be found after clicking the button of the drop-down menu, but some products can be found and displayed normally. What is the problem? Thanks!

Where is the problem and how to fix it ？
