When clicking on the Approve and reply on any comment, it generates this "red block"(see image ) and it is not clear whether the comment has been approved or not.

Please check your JS errors. It seems the problem comes from JS errors. Just press F12 and go to the Console tab and check JavaScript errors.
In case you want to say thank you! 🙂 We'd really appreciate if you leave a good review on the plugin page. This is the best way to say thank you to this project and the support team.
