adio appear cutted in half

Hi, the audio buttons started to appear cutted in half. Somebody knows the reason? I would be very grateful to find the reason of the problem as i spent many time creating that audio exercise. Thank you

It's just a question of width : it doesn't have enough width to display it. On my screen when the window is fullscreen the audio button are not cutted in half.

Maybe you can try to only show two column instead of three ?
