I can see what is happening. As Ajax triggers, it hides everything. This CSS is in your theme:

.woocommerce ul.products li.product .product-entry-slider {
    display: none;
}
.woocommerce ul.products li.product .woo-entry-image {
    display: none;
}

After a page loads, your theme is then using javascript to add inline a display: block; to these, plus much more to set the javascript working to make the sliders.

If this is done as a function, it is possible to trigger this again with some javascript from our FAQ Page, but you need to ask your theme developer. My guess is it is a function called oceanwpInitCarousel(). If you show the theme author this code:

<script>(function ( $ ) {
  "use strict";
  $(document).on("sf:ajaxfinish", ".searchandfilter", function(){
    console.log("ajax complete");
// load your WooCommerce carousel javascript here
  });
}(jQuery));</script>

They may advise you how to add that function.
