Every ticket booked is made through an "Office ID" which is attached to a specific country. Air France website is looking at this Office ID when displaying your booking and if you're on a Country Air France Website that does not match the country of the booking it will display this and invite you to use the matching website.
This is mainly due to manage bookings in the correct currency and rules attached to the country of the booking.
