Action bar is showing when using NoActionBar theme

I am using a theme with NoActionBar. Manifest file:

android:theme="@style/Theme.MaterialComponents.Light.NoActionBar"

I am using another Action bar, which I include to the layout:

<include layout="@layout/toolbar" />

However, I always get two Toolbars, and the upper one is the one, which would be there if I did not use NoActionBar theme. I found out, that if I delete this part in styles.xml file, it works as it should - there is no second action bar:

<style name="Theme.MaterialComponents.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
</style>

Of course I would like to keep this in the style.xml file as this helps to set up also the colour of the notification panel.

It seems to me this fails because Theme.MaterialComponents.Light.NoActionBar is an existant theme and you are creating it in the styles.xml so it overrides the existant one.

What I do is to create a new theme setting the one I want to edit as the parent theme:

<style name="AppNoActionBar" parent="Theme.MaterialComponents.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
</style>

And then set this new theme on the manifest:

android:theme="@style/AppNoActionBar"

This way you'll have the properties of the base theme (Theme.MaterialComponents.Light.NoActionBar) with the custom updates.
