Android studio navigation editor is not showing the fragment's attributes

I am using Navigation Editor in the android studio and my android studio version is 3.3.2.

my problem is when I add a fragment to the navigation editor, the attributes of the fragment are not showing in design mode. look at the picture:

enter image description here

mobile_navigation.xml

<?xml version="1.0" encoding="utf-8"?>
<navigation xmlns:tools="http://schemas.android.com/tools">
    <fragment id="@+id/currentWeatherFragment2"
              name="ir.houmansanati.forecastmvvm.ui.weather.current.CurrentWeatherFragment"
              label="current_weather_fragment" tools:layout="@layout/current_weather_fragment"/>
    <fragment id="@+id/futureListWeatherFragment4"
              name="ir.houmansanati.forecastmvvm.ui.weather.future.list.FutureListWeatherFragment"
              label="future_list_weather_fragment" tools:layout="@layout/future_list_weather_fragment"/>
    <fragment id="@+id/futureDetailWeatherFragment2"
              name="ir.houmansanati.forecastmvvm.ui.weather.future.detail.FutureDetailWeatherFragment"
              label="future_detail_weather_fragment" tools:layout="@layout/future_detail_weather_fragment"/>
    <fragment id="@+id/settingsFragment2" name="ir.houmansanati.forecastmvvm.ui.setting.SettingsFragment"
              label="SettingsFragment"/>
</navigation>

as you see my fragments in XML have name and label and id attributes but all of them are labeled as fragment. even when I set the attributes from the design mode after pressing Enter the text is gone but it changes in XML text.

I have tried Invalidate Caches/Restart but the problem still exists.

Any help?

You're using id=, name=, and label=. As per the Implementing Navigation documentation, these need to be android:id=, android:name=, and android:label=, respectively.

Note that your topmost <navigation> element must also contain xmlns:android="http://schemas.android.com/apk/res/android" in order to use the android: prefix.
