Do you know what makes templates collapse in the first place? Did you create the templates or copy them?

See Help:Collapsing to learn how to make elements collapsible. If you can't figure it out with the help page, I will help further.

The short answer is that your templates don't use the correct CSS classes for collapsing from what I can tell.
