当Radio采用循环输出时，校验无效，单独一项一项输入，则校验有效，何解？

前2个radio有效，后面的就都校验无效

<FormItem prop="env_type">
  <label class="share-label">环境类型：</label>
  <RadioGroup v-model="trackInfo.env_type" @on-change="changeAAA">
    **<Radio label="1">
      <Icon type="logo-apple"></Icon>
      <span>1</span>
    </Radio>
    <Radio label="2">
      <Icon type="logo-apple"></Icon>
      <span>2</span>
    </Radio>
    <Radio v-for="item in envList" :label="item.key" :key="item.key">
      <Icon type="logo-apple"></Icon>
      <span>{{item.value}}</span>
      <span class="share-desc">{{item.desc}}</span>
    </Radio>
  </RadioGroup>
</FormItem>
