Theme has 2 ways of user reviews. You can choose them in Theme options Reviews Type of user ratings
Important! Your Post must be “Review” to show user’s reviews.
Simple ratings. It is just 5 star rating function.
User reviews with criteria based on comment function and it allows to set full review with criteria. Your Post must have Review from Editor with criterias, so, these criterias will be used also for user review criterias.
If someone leave user review and you approve this review, your review box will show editor’s review score and user review score
How to make user reviews without Editor’s review
By default, User review criterias will have the same criterias as Editor’s review, so, you must have it in post. You can also make them work independently.
For this, go to Theme options and enable user reviews in Theme options Review Type of user ratings . Set show only users review
Also, if you have editor and user reviews, you can choose schema type. (This is for star snippet in Google). If you have popular site where people leave comments very often, I recommend schema based on user reviews.
