为什么我的代码重复了按钮的名称？

Question

我试图统一自定义我的按钮，但由于某种原因，按钮的名称在按钮的角落重复，无法自定义/删除。我如何摆脱重复？

public GUIStyle style;
public Texture Load;
public Texture backGroundTexture;



void OnGUI() {
    GUI.skin.button = style;
    GUI.DrawTexture (new Rect (0, 0, Screen.width, Screen.height), backGroundTexture, ScaleMode.ScaleToFit);
    //GUI.DrawTexture (new Rect (0, 0, 200, 73), Load, ScaleMode.ScaleToFit);
    if (GUI.Button (new Rect (Screen.width / 2.5f,Screen.height / 5 ,200,73), "Load")) {
        Application.LoadLevel(1);       
    }
    if (GUI.Button (new Rect (Screen.width / 2.5f, Screen.height / 3, Screen.width / 5, Screen.height/10), "Exit Game")) {
        Application.Quit();     
    }
}
