What happened?


What did you expect to happen?


How to reproduce it (as minimally and precisely as possible)?
1. start installer interactive shell to run alicloud install
2. When it comes to "Region" option, by default, the narrow is pointing the region to "ap-northeast-1"
[root@preserve-jialiu-ansible ~]# openshift-install create install-config --dir alidemo3
? SSH Public Key <none>
? Platform alibabacloud
? Region  [Use arrows to move, type to filter, ? for more help]
> ap-northeast-1 (Japan (Tokyo))
  ap-south-1 (India (Mumbai))
  ap-southeast-1 (Singapore)
  ap-southeast-2 (Australia (Sydney))
  ap-southeast-3 (Malaysia (Kuala Lumpur))
  ap-southeast-5 (Indonesia (Jakarta))
  ap-southeast-6 (Philippines (Manila))
3. Type "Enter"
[root@preserve-jialiu-ansible ~]# openshift-install create install-config --dir alidemo3
? SSH Public Key <none>
? Platform alibabacloud
? Region cn-hangzhou
? Base Domain [? for help]
4. The region is saved as "cn-hangzhou", but not "ap-northeast-1"

Anything else we need to know?
If move the arrow down or up to re-select "ap-northeast-1", the region is saved correctly
