Como os post em colunas 1-2 com vários itens?

Olá Senhores(as),

Estou com um problema em colocar os posts de uma das páginas em duas colunas.
Só a primeira coluna fica posta com os dois itens, as demais linhas das duas colunas os posts só ficam em um dos lados.
Eis como estou fazendo:

“[heading size=”28″ text_align=”center”]Colunistas[/heading]
[divider color=”#E7E7E7″]

[spacer size=”20″]
[column size=”1-2″ last=”0″]

[button link=”http://blitz.com/category/colunistas/hives/” target=”self” color=”#1abc9c” text=”light”]Meus Artigos[/button]
[button link=”#” target=”self” color=”#3498db” text=”light”]Meu Contato[/button]
[button link=”#” target=”self” color=”#e74c3c” text=”light”]Siga-me[/button]

[/author_info]

[/column]

[column size=”1-2″ last=”1″]

E ele não ficam em duas colunas e demais linhas na página, só na primeira….
Como posso resolver isso?
