After first clicked, Selector becomes smaller

Hello, i am using 1.2.2 When i start the activity the selector looks fine, but when i click the button or the segmented group itself, it becomes smaller and it doesnt fill the buttons.

            }
        };
        handler.postDelayed(runnable, 5000);
    }

    private void updateButton(int position) {
        button.setText("Position: " + position);
    }
}

edit: Also the example app looks like to be using different version of SegmentedButton, than whats in 1.2.2 edit: Tried version 1.1.1 and its working fine with the same code
