我有两个单选按钮组，我向其中添加了角度形式控件。我遇到的问题是，当我添加控件时，单选按钮分组消失了。此外，当我检查单选按钮时，它的name属性也消失了。结果是我无法再在不同的单选按钮组之间正确切换。我怎样才能解决这个问题？

TS：

import { Component, OnInit } from '@angular/core';
import { FormControl, FormGroup } from '@angular/forms';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent implements OnInit {
  formData = {
          "questions": [
            {
              "refCode": "Question1",
              "answers": [
                {
                  "refCode": "Question1Answer1",
                  "selected": true
                },
                {
                  "refCode": "Question1Answer2",
                  "selected": false
                }
              ]
            },
            {
