Change cat & subcat from being listed alphabetically in post header

Im using the theme Oblique. So I created the categories and subcategories for my posts, but once I published the post the categories are listed in alphabetical order instead of in the proper category, sub category, sub category order.

FOR EXAMPLE:

I write the post, then in the category section I checkmark next to:

North America
-USA
–Alaska
—Kotzebue

But then when I publish the post, under the heading of the post where the date, author, and categories are listed it says:

Alaska, Kotzebue, North America, USA

Is there any way to change that and make it go:

Kotzebue, Alaska, USA, North America

Or even in reverse is fine starting with North America. Just, having it in order would be nice.

Thanks for your help!
