Empty space at the top of the layout.

[LiamKe2]

I created the layout below. The result is that between the top border and the first button there is a space of around 2 buttons, that I don't see in other layouts. I don't know if I am adding something I should not.
I read the readme, and other things, but I cannot find an answer.
Thanks
