iview Autocompoent校验第一次可以，第二次总是校验不通过

Question

这个autoconpoent点击会触发一个事件

areaChange: function (value) {
        let address = this.addressTmp.find(item => {
          return item.fuzzyContent === value
        })
        if (address) {
          this.newData.countryZH = address.countryZH
          this.newData.countryEN = address.countryEN
          this.newData.province = address.provinceZH
          this.newData.provinceEN = address.province
          this.newData.city = address.cityZH
          this.newData.cityEN = address.city
          this.newData.district = address.districtZH
          this.newData.districtEN = address.district
          this.newData.town = address.townZH
          this.newData.townEN = address.town
          this.fuzzyContent = value
        }
      },
      

我校验的就是这个newData.countryEN
我第一次打开这个modal的话，校验过了
第二次打开modal，虽然有值但是校验失败了

下面是前端代码

 <Form ref="newData" :model="newData" :rules="newDataValidate" compact>
          <Form-item :label="$t('address')" size="small" prop="countryEN">
            ---{{newData.countryEN}}
            <AutoComplete
              v-model="pageParams.queryParam"
              @on-change="addressSearch"
              @on-select="areaChange"
              :placeholder="$t('area')">
              <div>
                <Option v-for="item in addressTmp" :value="item.fuzzyContent" :key="item.id">
                  <div class="title-info" v-html="item.fuzzyContentShow"></div>
                </Option>
              </div>
            </AutoComplete>
          </Form-item>
          
          
          
          
    

data () {
return {

isShow: false,
isShowAdd: false,
actived: -1,
opts: [],
data: {},
area: [],
newData: {countryEN: ''},
newDataValidate: {
  countryEN: [{
    required: true,
    message: this.$t(`isRequired`, {msg: this.$t(`area`)}),
    trigger: 'blur, change'
  }],
