操作代码：

//列发生改变时
deliveryColumnChange: function(e) {
    var value = e.detail.value;
    var carrier = this.data.carrierList;
    var carrierSelect = this.data.carrierSelect;
    carrierSelect[e.detail.column] = value;

    switch (e.detail.column) {
      case 0:
        carrierSelect[0] = value;
        carrier[1] = this.data.carrierArray[value];
        break;
      case 1:
        carrierSelect[1] = value;
        break;
    }

    this.setData({
      carrierList: carrier,
      carrierSelect: carrierSelect
    });
},

//确定
deliveryChange: function (e) {
    var value = e.detail.value;
    
    this.setData({
      carrierSelect: value,
      carrierSelected: value,
    });
},

//取消
cancelDelivery: function(e){
    var carrier = this.data.carrierList;
    var carrierSelected = this.data.carrierSelected;
    carrier[1] = this.data.carrierArray[carrierSelected[0]][carrierSelected[1]];
    this.setData({
      carrierSelected: carrierSelected,
      carrierSelect: carrierSelected,
      carrierList: carrier,
    })
},

点击取消后再次点开选择器，如下图

列表数据都正常，但是选择器里没有渲染出来，是我代码有问题还是小程序组件的bug，麻烦大佬们解答一下，谢谢。
