For the comment meta, as i said previously above, we don’t have any additional code for comment meta. It will use default code for WordPress comment.
If you want to delete it, you can follow the instruction on this article http://www.wpbeginner.com/wp-themes/how-to-remove-date-and-time-from-wordpress-comments/. Did you’ve tried it before? or it doesn’t work on your side? Let me know if you need a help in there.
