I am trying to add Arabic language. I have configured package correctly but some labels are translated some are not

[Yamesh1994]

Here is my app initializer and App Factory

export function HttpLoaderFactory(http: HttpClient) {
return new TranslateHttpLoader(http, environment.apiUrl + 'localizations/json/', '.json');
}

export function appInitializerFactory(translate: TranslateService, injector: Injector, http: HttpClient, authService: LmsAuthService) {
return () => new Promise((resolve: any) => {
const locationInitialized = injector.get(LOCATION_INITIALIZED, Promise.resolve(null));
locationInitialized.then(() => {
http.get(environment.apiUrl + 'get-default-lang')
.subscribe(responseData => {

      const langToSet = responseData.code;
      translate.setDefaultLang('en-US');
      if (authService.getToken().length > 10) {
        http.get<any>(environment.apiUrl + 'user').subscribe((data: any) => {

          translate.use(data.data.language).subscribe(() => {
            console.info(`Successfully initializedd '${data.data.language}' language.'`);
            localStorage.setItem('language', data.data.language);
          })


        }, err => {
          // console.log(err);
          console.error(`Problem with '${langToSet}' language initialization.'`);
        }, () => {
          resolve(null);


        });
      }
      else {
        translate.use(langToSet).subscribe(() => {
          console.info(`Successfully initialized '${langToSet}' language.'`);
          localStorage.setItem('language', responseData.code);
        }, err => {
          // console.log(err);
          console.error(`Problem with '${langToSet}' language initialization.'`);
        }, () => {
          resolve(null);
        });
      }
    },

      err => {
        console.error('API error:', err);
        resolve(null);
      });
});

});
}
