Blog layout on demo site different to my one

Hi WPMU Team,

the Blog layout on your demo site looks quite different to my one.
Your demo site: http://demo.upfront.pro/spirit/2015/10/06/healthy-life-starts-today/

My demo blog: http://pommern.immobilien/blog/2015/10/27/blog-001-travel-to-bogota/

e.g. the date is on the right side and the category is not displayed on your demo. How can I change my one to have your layout?

Many thanks in advance,

Kind regards,
Markus
