I solve this issue with changing theme preference Theme.Leanback

On your manifest file :

<activity android:name=".ui.setting.YourSettingPrefActivity"
        android:exported="true"
        android:theme="@style/Theme.Pref.LeanbackPreferences"/>

And here on styles.xml

<style name="Theme.Pref.LeanbackPreferences" parent="Theme.Leanback">
    <item name="preferenceTheme">@style/PreferenceThemeOverlay.v14.Leanback</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:backgroundDimEnabled">true</item>
    <item name="android:colorPrimary">@color/fastlane_background</item>
</style>
