Problemas com transition no chrome

Oi pessoal o problema é o seguinte.

Tenho alguns efeitos transition no css que são para acontecer com o click dos botões. Só que no chrome eles acontecem junto com carregamento da pagina saindo do topo e descendo.

Acessem o site e cliquem em empresa e home no firefox e no chrome pra voces verem.
