Hello,
The problem appears on the category page only. You provided a link to the shop page on our demo. On the shop page, it works on your site too.
If you check the category page on our demo you’ll see the same https://xstore.8theme.com/demos/2/home-decor/product-category/rug-decor/?et_per_page=6
So, if you want to show category description on the pagination page you need to contact WooCommerce support because it’s related to plugin code https://prnt.sc/1skm58v
https://github.com/woocommerce/woocommerce/blob/0a857088f994def1aca6f3feb3e4a4af964b225f/includes/wc-template-functions.php
We can do nothing with this from our side, unfortunately.
Regards
