ngx-translate不正常工作，即使我设置translate.setDefaultLang('en')

Question

我用的是 fa 和 en 我的应用程序的语言。有两个按钮，应该是点击后改变方向和语言。setDir(code) 功能。在点击按钮后，应用程序将被重新加载，语言和方向发生变化，但ngx-translation不能正常工作。语言和方向改变了，但ngx-translation不能正常工作。它总是显示fa.json文件的值。即使我设置了 translate.setDefaultLang('en').

app.component.ts:

import { Component } from '@angular/core';
import { Platform, ModalController } from 'ionic-angular';
import { StatusBar } from '@ionic-native/status-bar';
import { Storage } from '@ionic/storage';
import { TranslateService } from '@ngx-translate/core';
export class MyApp {
  constructor(public platform: Platform, private storage: Storage,
translate: TranslateService, private modalController: ModalController,
statusBar: StatusBar) {
platform.ready().then(() => {
  statusBar.styleDefault();
  this.splash = modalController.create(SplashPage);
  this.splash.present();
});
translate.setDefaultLang('en');
storage.get('languageCode').then((lang) => {
  platform.setLang(lang, true);
  translate.use(lang);
});
this.storage.get('myDir').then((dir) => {
  platform.setDir(dir, true);
});
  }
  async setDir(code) {
    if (code === "fa") {
      await this.storage.set('myDir', 'rtl');
      await this.storage.set('languageCode', 'fa');
      window.location.reload();
    } else {
      await this.storage.set('myDir', 'ltr');
      await this.storage.set('languageCode', 'en');
      window.location.reload();
    }
  }
}

app.html

<ion-item text-end color="none" menuClose="" id="lis-sell" class="mymenu">
{{'simple_sale' | translate}}
</ion-item>

fa.json

{
"simple_sale": "فروش"
}

en.json

{
"simple_sale": "sale"
}

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { IonicApp, IonicModule, IonicErrorHandler } from 'ionic-angular';

哇。我觉得很愚蠢。一切都很好。它只是我已经定义了两个单独的菜单，我使用ngx-translate的菜单中的值。一个菜单工作在rtl。
