Dear Undalkeor,
please try using last=”1″ on each column that is supposed to be the last one on its line – there is no way the system can know where we want to break the line, thus we need to hint at it with a small addition to the shortcode. The full code for a last column in a line would look like:
[column size=”1-2″ last=”1″]This is column text[/column]
There is some additional information on this in the manual, page 13 ;)
Sincerely,
Andrew | Satori
