spread运算符未将值设置为正确的状态

我有一个奇怪的问题,当我试图设置我的状态在我的减速器。

state = {
  ...state,
  activeChannel: action.payload.channelList[0].name
    .replace("&", "and")
    .replace("`", "")
    .replace("'", "")
    .replace("-", "")
    .replace(/\s/g, "")
    .toLowerCase(),
  preferedChannelsList: channelObjectTemp
};

当我控制台.log但通道状态设置不正确。

我使用扩展运算符的方式有什么问题吗?

减速器代码更新

    switch (action.type) {
      case GET_CHANNEL:
        let totalNumberOfStories=0;
        let activeChannelList=action.payload.channelList.slice(0,lazyLoadingStep);
        let channelObjectTemp= {
            ...state.preferedChannelsList,
           [action.payload.channelList[0].name.replace("&","and").replace("`","").replace("'","").replace('-','').replace(/\s/g, '').toLowerCase()]:action.payload.channelList[0]};


        state={...state,activeChannel: action.payload.channelList[0].name.replace("&","and").replace("`","").replace("'","").replace('-','').replace(/\s/g, '').toLowerCase(),
            "preferedChannelsList":channelObjectTemp };
        break;
