Why I can't choose managed instance group I created when setting up http load balancer in gcloud?

Question

I'm trying to setup http load balancer, with auto-scaling enabled managed instance group for the back-end service.

The problem occurs when I tried to add instance groups while creating backend service, I already made my managed instance group from an instance template, but I can't see it from adding instance group panel. I chose 'select from existing groups'(not sure it's exact phrase for I'm using foreign language) and I selected asia region, but I couldn't see/select the group i created.

It gives "no instance groups in this region" message when I choose other regions like US/EU, so I guess it recognizes my group but it just doesn't show up.

http load balancer doesn't support asia region or should I have to modify some other settings to see my group?

fyi, I tried all above action on the cloud console (not with command line)

Any helps would really be appreciated!

Best, JP

There's currently a bug preventing existing instance groups from appearing in the drop-down menu. Until it's fixed, you can add them via gcloud using this command: gcloud compute backend-services add-backend [backend-service-name] --instance-group [instance-group-name].
