Updating addresses on clients and creating new clients with addresses

Hi,

We are creating new clients in Servicem8 and updating them as well. According to the API documentation there is the following fields in clients that can be updated or added.

address_street
address_city
address_state
address_postcode
address_country
address
billing_address

When posting to servicem8 the only 2 fields that appear to work are the "address" and "billing_address" fields.

On the client billing details card in Servicem8 there is a breakdown of the individual street information. However, the "billing_address" only updates the address field and the other fields are not updated.

What are these fields for? address_street
address_city
address_state
address_postcode
address_country

And how do we update the individual address details on the client billing card?
