I think it’s a glitch. The same happened to me when I booked 5 nights at WA Maldives. It showed up as 480k points + $12k+ euro’s. I told the hotel and they fixed it right away. I also had a one night reservation at the same hotel completely disappear from my profile. It couldn’t even be seen my the diamond desk. But the hotel still had the reservation. I ended up having to cancel that night so I had to do so directly through the hotel.
