Indented Android PreferenceFragment

I'm not exactly sure why this is happening, but when I create my preferences fragment. All of the preferences in a preference category are indented. When I do this in a smaller app, the settings appear just fine. Any ideas?

public class SettingsFragment extends PreferenceFragment {


public SettingsFragment() {
    // Required empty public constructor
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    addPreferencesFromResource(R.xml.fragment_settings);
}

}

<?xml version="1.0" encoding="utf-8"?>

<PreferenceCategory android:title="Game Setup">

    <CheckBoxPreference
        android:key="checkbox_randomize_opponents"
        android:title="Randomize Opponents"
        android:summary="Randomize opponents after round 1" />

</PreferenceCategory>

        int id = item.getItemId();
    switch (id) {

        case R.id.action_settings:

        Fragment f = getFragmentManager().findFragmentByTag("settings_frag");

        if (f == null)
            f = new SettingsFragment();

        getFragmentManager().beginTransaction().addToBackStack("settings").replace(android.R.id.content, f, "settings_frag").commit();
        return true;
