Javascript stacknavigator与抽屉导航器嵌套时标题不起作用

我有三个导航器，AuthStackNavigator for Auth，DrawerNavigator和AppStackNavigator。因此，AuthStackNavigator嵌套到DroperNavigator，DroperNavigator嵌套到AppStackNavigator

问题是，当从DroperNavigator导航到AppStackNavigator时，它会继续显示DroperNavigator的标题，但预期的是AppStackNavigator的标题。（到目前为止，我已经提到了header:null，因为它显示了双header）如何解决这个问题

导航器代码：

   const AppStackNavigator = createStackNavigator({
Home: {
screen: Home,
navigationOptions: {
 header: null
}
},
StoreList: {
screen: StoreList,
navigationOptions: {
  header: null
 }
 },
});

const DrawerNavigator = createDrawerNavigator({
Dashboard: {
  screen: AppStackNavigator,
  navigationOptions: {
    drawerLabel: "Home",
  }
},
Training: {
  screen: Training,
  navigationOptions: {
    drawerLabel: "Training"
  }
},
RoutePlan: {
  screen: RouteCalendar,
  navigationOptions: {
    drawerLabel: "Route Plan"
  }
}
},
{
contentOptions: {
  activeTintColor: '#127CC1',
},
contentComponent: props => <DrawerComponent {...props}/>,
drawerOpenRoute: 'DrawerOpen',
drawerCloseRoute: 'DrawerClose',
drawerToggleRoute: 'DrawerToggle',
navigationOptions : ({navigation}) => {
  const { routeName } = navigation.state.routes[navigation.state.index];
  const headerTitle = routeName;
  return {
      headerTitle,
      headerLeft: (
        <Icon name="md-menu" style={{ marginLeft: 10 }} 
        onPress={() => navigation.toggleDrawer()}
        />
      )
    }
  }
 }
);

const AuthStackNavigator = createStackNavigator(
{
LoginScreen: {
screen: Login,
navigationOptions: {
  headerTransparent: true
}
},
 Drawer: DrawerNavigator,
});

const AppStackNavigator=createStackNavigator({
主页：{
屏幕：主页，
导航选项：{
标题：空
}
},
门店列表：{
屏幕：StoreList，
导航选项：{
标题：空
}
},
});
const pawernavigator=createpawernavigator({
仪表板：{
屏幕：AppStackNavigator，
导航选项：{
抽屉标签：“家”，
}
},
培训：{
屏幕：培训，
导航选项：{
抽屉标签：“培训”
}
},
路线规划：{
屏幕：RouteCalendar，
导航选项：{
抽屉标签：“路线图”
}
}
},
{
内容选项：{
activeTintColor:“#127CC1”，
},
contentComponent:props=>，
DropeRopenRoute:“DropeRopen”，
抽屉关闭路线：“抽屉关闭”，
DroperTogglerOute:“DroperToggle”，
导航选项：（{navigation}）=>{
const{routeName}=navigation.state.routes[navigation.state.index]；
const headerTitle=路由名称；
返回{
海德特尔，
左校长：(
navigation.toggleDrawer（）}
/>
)
}
}
}
);
const AuthStackNavigator=createStackNavigator(
{
登录筛选：{
屏幕：登录，
导航选项：{
校长：是的
}
},
出票人：出票人，
});
