You are welcome.
However, by the solution provided by them, there is still one difference, the placement of rating count is underneath the rating stars rather than next to the rating stars as it is from the original woocommerce.

Big thanks, Hannah! This plugin “Health Check” is pretty useful. Through troubleshooting mode in this plugin, I found out it seems like thee is a conflict between woocommerce and flatsome theme that I am using.
I asked the theme for the support and they asked me to try have this below added in my CSS and it worked :

.woocommerce-review-link {
opacity:1 !important;
position:relative !important;
}

I am not sure if this a global issue from this theme and whether all other flatsome theme users are having the same issues but hopefully this issue will not appear again with any updates later.

Thanks for the help.
