Template different for each categories

I have two categories and some subscription plans.
When I show with the menu list of categories:
geo4all.it/afcea/index.php/come-associarsi
and then click on the first "Socio Singolo" : geo4all.it/afcea/index.php/socio-singolo
I have the correct template.
If I click on the second category: "Socio Corporate" : geo4all.it/afcea/index.php/socio-corporate ,
I have another template (column based). Why? I would have the same template for both.
