Default Template Widgets

How do you alter the widgets showing on the default template?

I can’t see where they are affected on the widget page.

http://test.nichols.org.uk/booking/availability/ [content & sidebar]

I can see where the ‘sidebar’ widgets are included but not the ‘default’ ones.

Thanks!
