The reason for this discrepancy is that the review section on Location level can also contain questions or photos. Such a "review" does not contain an actual rating.
On the Global Dashboard, we only display the amount of the actual reviews (with ratings).
Therefore, we will show:
- on the location level or on the location list: the sum of the total reviews (including photos and questions)
- whilst on the global dashboard (multi locations), we will show the sum of total reviews (excluding photos and questions).
