LWC Input Address not populating Province [closed]

Question

I'm trying to implement a standard lwc input address in a custom LWC component. https://developer.salesforce.com/docs/component-library/bundle/lightning-input-address/example.

When I search an Italian address, the province field is not populated when I select an address result. as you can see in the screen below.

In the picklist of results search I can see the province code (for example: Roma --> RM). (green box)

Do you have suggestions to work around the problem?

my code:

<lightning-input-address  address-label="Shipping Address"
            street-label="Street"
            city-label="City"
            country-label="Country"
            province-label="Province"
            postal-code-label="PostalCode"
            street=""
            city=""
            country=""
            province=""
            postal-code=""
            required
            onchange={addressInputChange}
            field-level-help="Select Shipping Address"
            show-address-lookup>
         </lightning-input-address>



addressInputChange(event){

    const address = this.template.querySelector('lightning-input-address');

    console.log('Street is ' , event.target.street);
    console.log('City is ' , event.target.city);
    console.log('Province is ' , event.target.province);
    console.log('Country is ' , event.target.country);
    console.log('postal Code is ' , event.target.postalCode);


    }
