Hi @tharindu1995,
Could you please provide us with a screenshot so that we can see what you are describing?
I recommend https://snipboard.io for sharing screenshots – please follow the instructions on the page, then paste the URL here. It works with Chrome, Firefox, Safari, and Edge.
Additionally, are you using a plugin to add the star rating or you’re using the core WooCommerce rating functionality?
Could you please share a copy of your site’s System Status? You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”.? Once you’ve done that, paste it here in your response.
