GUI image changing

[callimuc]

Hey there. After I was reading a tutorial how to change the default GUI images, I was trying out on that. But when I wanted to try out on buttons, I got the following fail. Idk if its with more GUI tools.
The text of the GUI button isn´t centered anymore. It´s aligned left now.
Here is a small screenshot:



When I use the default GUI style, everything works fine. Here´s the script part:

PHP Code:

    new GuiButtonCtrl("TestDesignButton") {
      useOwnProfile = true;
      profile.bitmap = "callimuc_guibutton-profile.png";
      //even tried profile.bitmap = "callimuc_guibutton-profile"; also shows the image but also with the fail
      profile.fontSize = 12;
      profile.fontStyle = "b";
      profile.fontType = "Arial";
      x = 6;
      y = 130;
      position = {6, 130};
      extent = {88, 20};
      text = "Load";
    }
