Please ignore whatever "number" is showing in the display under ANY thread. Instead click that link and you will find the correct number of reviews LISTED.
Since approx June last year, the review counter has not been working, so those who already had a review up until then.... the system still quotes the number of reviews up to that point in June 2019, i.e. it does not add the number of reviews posted since that date, whether Positive or Negative review.
For any profile which had reviews submitted for the first time AFTER June 2019, their review count shows ZERO, but when you then click on that, the true exact number of reviews posted since their first review appeared are ALL shown.
Hope this makes sense.
