You are right !

Thanks for bringing this to our attention ...
Sloppy encoding backoffice or shrewd programming....

to be honest,
when searching for rewards rooms the app shows default setting occupancy for 1 person ....

I think if you book an award stay at rate (seeing 32.000 pts) if mailing reservations
that 2 will be the occupancy instead of 1
that won't incur any extra surcharge
