ui-form表单校验select有问题

 <uni-forms ref="calcForm" :modelValue="formData" :rules="rules" :label-width="200">  
          <uni-forms-item  
            label="性别"  
            name="sex"  
            required  
            :rules="[{ required: true, message: '请选择性别' }]"  
          >  
            <uni-data-select v-model="formData.sex" :localdata="sexRange"></uni-data-select>  
          </uni-forms-item>

校验无效果，直接跳出成功，不选中无所谓
