Issue when setting both Default Billing and Default Shipping addresses

[lanadmina24d39]

Hi,

There seems to be an issue when trying to update/add a contact and set their default billing and default shipping in a single request with the Magento 2's Admin API. In the parameters I have set the addresses and used default_billing & default_shipping which have been set to True, but in the api response only one of these default addresses get set. Sometimes the default_billing is set but not the default_shipping or sometimes the default_shipping is set but not the default_billing. 

Below is an example of the parameters I have sent the API and the response I have received. Despite setting both default_billing & default_shipping in the parameters, the response only returned the default_shipping. I believe this is a bug.

Parameters:

{
  "customer": {
    "id": "4792",
    "email": "lan-test@a2zcloud.eu.com",
    "firstname": "Bradley",
    "lastname": "Duncan",
    "addresses": [
      {
        "telephone": "N/A",
        "firstname": "Bradley",
        "lastname": "Duncan",
        "street": [
          "40 Boughton Rd"
        ],
        "city": "WHYGATE",
        "postcode": "NE48 8SZ",

        },
        "region_id": 0,
        "countryId": "GB",
        "default_billing": true
      },
      {

        "lastname": "Duncan",
        "street": [
          "24 milford street1"
        ],
        "city": "salisbury",
        "postcode": "SP1 2AP",
        "region": {

          "region": "wiltshire",
          "region_id": 0
        },
        "region_id": 0,
        "countryId": "GB",
        "default_shipping": true
      }
    ],
    "website_id": 1
  }
}
