Chrome Autofill triggering separately for billing and contact information

Question

Autofill is triggering separately for billing and for contact information.

For example, when I click on any of the following 4 input fills it offers autofill for them => first name, last name, phone number and email. When I click on any of the following 4 it triggers autofill for them together => billing address, billing postal-code, billing country, billing city.

Autofill works well for each of the two groups, but I want it to be one group that will autofill by selecting any of the 8 input fields.

Code example (I'm using Angular 8 with Material design components but I think this shouldn't pose as a distraction since I see this as a HTML issue):

<form method="post" id="paymentForm" [formGroup]="formGroup" (ngSubmit)="onSubmit(formGroup.value)" class="form" >

    <div class="customer-info">
        <div class="customer-info-personal">
            <div>
                <mat-form-field class="form-element">
                    <input name="fname" matInput placeholder="Ime" formControlName="firstName" autocomplete="given-name" form="paymentForm">
                    <mat-error
                        *ngIf="!formGroup.controls['firstName'].valid && formGroup.controls['firstName'].touched">
                    </mat-error>
                </mat-form-field>
                <mat-form-field class="form-element">
                    <input name="lname" matInput placeholder="Prezime" formControlName="lastName" autocomplete="family-name" form="paymentForm">

Answer 1

Fixed it by removing the word billing from autocomplete values and bill- from name values.

E.g.

Before autocomplete="billing postal-code" name="zip"

Before autocomplete="postal-code" name="zip"

Changing the autocomplete field alone proved to be enough.
