The city is not being added to the address here, it jumps right from District 1 to Vietnam skipping Ho Chi Minh City.

If you click on the details, it seems like it can tell that it's within the city but is greyed out (in the api it's represented as `isaddress=false`).

Is this an intentional choice? Or a misconfiguration?
