Two-way data binding, null values

I am having an issue with two way data binding and Angular 8

In the following example, my model (service.formData) is populated, but one of the variables (which is really a child table) is null (service.formData.ProjectSshaspModel). If I populate data in the database, the two way binding seems to work ok and retrieves and passes data back. But when the variable is null when the page loads, and I populate the model (HTML page), the object does not seem to get populated

I have placed both the HMTL, Angular data binding and JSON values below.

<form #form="ngForm" autocomplete="off" (submit)="OnSubmit(form)" *ngIf="service.formData">
<div class="row" id="section1">
<div class="col-md-10">

<input type="hidden" name="ProjectID" #ProjectID="ngModel" [(ngModel)]="service.formData.ProjectID" />
<input type="hidden" name="ProjectSshaspModel.ProjectSshaspID" #ProjectSshaspModel.ProjectSshaspID="ngModel" [(ngModel)]="service.formData.ProjectSshaspModel.ProjectSshaspID" />
<input type="radio" id="not-required"
name="CompanyLogoRequired" #ProjectSshaspModel.CompanyLogoRequired="ngModel" [(ngModel)]="service.formData.ProjectSshaspModel && service.formData.ProjectSshaspModel.CompanyLogoRequired" ng-checked="(CompanyLogoRequired==0)" [value]="0" />
Not Required

<input type="radio" id="incorporate"
name="CompanyLogoRequired" #ProjectSshaspModel.CompanyLogoRequired="ngModel" [(ngModel)]="service.formData.ProjectSshaspModel && service.formData.ProjectSshaspModel.CompanyLogoRequired" ng-checked="(CompanyLogoRequired==1)" [value]="1" />
