Notification text change only once

So I am translating my application but I am facing annoying problem.

I have a service with foreground notification with 2 action buttons.

When I select the language in the main activity,the app works great with the translation strings.However,lets say I choose english and the service notification started,the notification text is in english for the first time,but when I get back to the application and minimize the app again,the text of the service notification is changed to the other language without me doing anything.

Service detect language code ( onCreate ):

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {        if (MainActivity.LANG_CURRENT.equals("en")) {            changeLang(getApplicationContext(),"en");        } else {            changeLang(getApplicationContext(),"iw");        }    }

Service Notification code:

    channelName = "Background Service";    NotificationChannel chan = new NotificationChannel(NOTIFICATION_CHANNEL_ID, channelName,   NotificationManager.IMPORTANCE_HIGH);    chan.setLightColor(Color.BLUE);    chan.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);    manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);    assert manager != null;    manager.createNotificationChannel(chan);    Intent intentExit = new Intent(this, BackgroundLocation.class);    intentExit.putExtra(EXIT_APP_NOTI, true);    sendBroadcast(intentExit);    // The PendingIntent that leads to a call to onStartCommand() in this service.    PendingIntent servicePendingIntent = PendingIntent.getService(this, 0, intentExit,            PendingIntent.FLAG_CANCEL_CURRENT);    Intent i = new Intent(getApplicationContext(), MapsActivity.class);    i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);    PendingIntent activityPendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, i, 0);    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {        if (MainActivity.LANG_CURRENT.equals("en")) {            changeLang(getApplicationContext(),"en");        } else {            changeLang(getApplicationContext(),"iw");        }    }    NotificationCompat.Action action = new NotificationCompat.Action(R.drawable.ic_launch, getString(R.string.launch), activityPendingIntent);    NotificationCompat.Action action2 = new NotificationCompat.Action(R.drawable.ic_cancel, getString(R.string.stop), servicePendingIntent);    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);    Notification notification = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID)            .setContentTitle("App is running in background")            .addAction(action)            .addAction(action2)            .setColor(getColor(R.color.foreGroundBackgroundColor))            .setPriority(NotificationManager.IMPORTANCE_HIGH)            .setCategory(Notification.CATEGORY_SERVICE)            .setSmallIcon(R.drawable.applogo)            .build();    startForeground(2, notification);

Thank you for your help !
