Failed Access Denied: S3 properties on us-east-1 region

When I created s3 buckets at each regions including us-east-1, us-west1, us-west-2, and ap-northeast-1 and applied the IAM policies below to a IAM group. I got some of the properties of other than us-east-1 region somehow.
I created an IAM group and attached two IAM policies with the group.

IAM policy to define the buckets to operate and access source IP address.

{
  "Statement": [
    {
      "Condition": {
        "IpAddress": {
          "aws:SourceIp": [
            "xxx.xxx.xxx.xxx/32",
            "xxx.xxx.xxx.xxx/32"
          ]
        }
      },
      "Resource": [
        "arn:aws:s3:::bucket_name.ap-northeast-1",
        "arn:aws:s3:::bucket_name.ap-northeast-1/*",
        "arn:aws:s3:::bucket_name.us-west-1",
        "arn:aws:s3:::bucket_name.us-west-1/*",
        "arn:aws:s3:::bucket_name.us-west-1",
        "arn:aws:s3:::bucket_name.us-west-1/*",
        "arn:aws:s3:::bucket_name.us-west-2",
        "arn:aws:s3:::bucket_name.us-west-2/*"
      ],
      "Action": "s3:*",
      "Effect": "Allow"
    }
  ],
  "Version": "2012-10-17"
}

• IAM policy to list all the buckets for a s3 tool like S3 Browser

{
  "Statement": [
    {
      "Resource": "*",
      "Action": "s3:List*",
      "Effect": "Allow"
    }
  ],
  "Version": "2012-10-17"
}

I got the properties of us-west-1, us-west-2, ap-northeast-1, but couldn't get those of us-east-1, though the same IAM policies are applied.


I successfully got the properties of us-east-1 after adding the action as follows.

{
  "Statement": [
    {
      "Resource": "*",
      "Action": [
        "s3:List*",
        "s3:Get*"
      ],
      "Effect": "Allow"
    }
  ],
  "Version": "2012-10-17"
}

I am wondering if us-east-1 (US standard) region is different from other regions in how to apply IAM policy because it is the 1st region of AWS???
