[SOLVED] Android icons and radio buttons not following day/night mode

After creating a very basic Settings AppCompatActivity and PreferenceFragmentCompat to change the day/night mode of my application, but the light theme doesn't seem to apply across the entire application. None of the icons in the rest of the application want to follow, and the radio buttons in the ListPreference dialog also seem to retain their original dark theme. What am I doing wrong here?

SettingsActivity.java

public class SettingsActivity extends AppCompatActivity {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_settings);
        getSupportFragmentManager().beginTransaction().replace(R.id.settingsFrame, new SettingsFragment()).commit();
    }

    public static class SettingsFragment extends PreferenceFragmentCompat {

        @Override
        public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
            setPreferencesFromResource(R.xml.settings, rootKey);

            findPreference(getString(R.string.pref_theme)).setOnPreferenceChangeListener((preference, newValue) -> {
                if (newValue.toString().equals(getString(R.string.light))) {
                    AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);
                } else if (newValue.toString().equals(getString(R.string.dark))) {
                    AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);
                } else {
                    AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_FOLLOW_SYSTEM);
                }
                return true;
            });
        }
    }
}
