Hello, Bhabani
1/ Filters styles are broken on your site it can be due to a 3rd party plugin effect on it.
If you want to disable mentioned filters, add the next code in Theme Options > Theme custom CSS > Global:
.woocommerce-page .woocommerce-ordering, .woocommerce-page .view-switcher, .woocommerce-page .products-per-page {
display: none;
}
2/ Disable WooCommerce Infinite Scroll and Ajax Pagination plugin or set correct settings – https://xstore.helpscoutdocs.com/article/65-woocommerce-infinite-scroll-and-ajax-pagination-settings
