Why can't I bind a public address range at creation or delete one that's already bound?

Why can't I bind a public address range at creation or delete one that's already bound?

You can now create and use public address ranges in the Frankfurt and Madrid regions, if your account has been approved for access. To request access to Public Address Ranges for VPC, contact your IBM representative.

Binding a public address range during creation or deleting a bound range fails due to insufficient permissions.

You won't be able to create or delete the public address range.

Insufficient IAM role or required IAM actions.

To perform these tasks, you must first have either the Administrator or Editor IAM role. To create a public address range, the action is.public-address-range.public-address-range.create is required. To delete a public address range, is.public-address-range.public-address-range.delete is necessary. If the public address range is to be bound during creation, or is already bound when you want to delete the range, you must also have the is.vpc.vpc.operate permission.
