Lighweight Grid Columns

Hi,

I'm having a slight layout issue on tablets and mobiles using Lightweight Grid Columns plugin.

I'm using this shortcode:

[lgc_column grid="10" tablet_grid="0" mobile_grid="0"]
[/lgc_column]

[lgc_column grid="80" tablet_grid="100" mobile_grid="100”]
Lorem Ipsum Dolor Sit
[/lgc_column]

[lgc_column grid="10" tablet_grid="0" mobile_grid="0" last="true"]
[/lgc_column]

But when I view the page on mobile or tablet there is lots of white space at the very top and bottom.

You can see what I mean here: http://www.freshoffice.ie/1634-2/.

How can I solve this?

Thank you.
