Thanks all. Just as a follow-up, the Customer Service Ambassador called me tonight, hoping I would answer the phone.
This gentleman gave me a full and complete resolution, easily explained.
Very simple once explained. The guest posted the review in Quebec French. Reviews get posted first by language of reviewer and then by date. So in this case, all the English reviews appeared first (because my language is English), by date and then next are the French (and other languages) reviews by date. Hope this helps and makes sense.
Kudos to the efforts, dedication and professionalism he presented! I think we both learned a lot.
