Woocommerce results page

Hi,I am using the ajax search plugin along with WooCommerce and Avada theme. I am facing a problem when I get redirected to woocommerce results page.

I have configured your plugin to search only for products, redirect to Woocommerce results page and override the default WordPress search results with results from this search instance. I have set the number of results per page to 12, witch is the same value used on my theme settings.

Now, when I search for “ομαδικά” (sorry for that, the site is in Greek) and click on the magnifier icon, I get redirected to woocommerce results page that is displaying 3 products and not 12. The second page displays 8 results, the third 8 again, the fourth 4, the fifth 3 and so on . I am attaching some photos so you can see what I am talking about.

I get the same issue even with the Twenty Twenty theme and with all plugins disabled. Any ideas?
