What is the Product review "Summary Rating"?

[nobuttsalex]

When adding/editing a product review in the back-end there is a field of "Summary Rating" however it always has the message "Rating isn't Available". How and when is this Summary Rating used?

After having a poke around Magento's code, I commented out 2 lines and got the summary rating showing. I guess it is a bug in Magento and it is meant to look like this:

Any more info about this? Is this really a bug? I'm unable to see neither the "Summary Rating" nor the "Detailed Rating" on Magento 2.1.1.

Hello,

I've got the same problem at first.

Without needing to change the code, it was possible to first:

Go to Stores - Ratings

and select the right view for all 3 ratings.

Afterwards my stars showed up in frontend and admin panel.
