I am unable to reproduce this.
Are you seeing any entries in the Site Reviews > Tools > Console?
in console:
[2019-10-29 13:26:13] NOTICE [helpers.php:68] Recalculated rating counts.
reviews are published on the site and are displayed normally
On the page for editing reviews, in the “details” section, the names of the authors are indicated, however on the site all authors are designated as anonymous.
Are you using any code snippets in your theme’s functions.php file, or using any advanced customisations? Are you using any custom plugin templates in your theme?
Since there has been no reply, I will mark this as resolved.
