I only get excerpt of imported blogs

My feed is not working properly. I have set up the site http://wennerbergconsulting.se/ to get blog posts from http://www.medtechmagazine.se/category/anders-wennerberg/feed/ but I only get a short excerpt eventhough I have set "full post" import. Is there anything that need to be set/changed on the source blog? I have access to that site as well.
