having issues with urls

I have setup the pages and activated the addons for category and profile, but any time I try follow them I get strange behavior.
The archive page works fine: https://jimiwikman.se/fragearkiv/
The post page is ok (need to override some behavior from the theme): https://jimiwikman.se/fragearkiv/fraga/vilket-ar-det-basta-pluginet-for-test-i-jira/
My Profile link give a strange 404 and show blogposts: https://jimiwikman.se/fragearkiv/vara-fragvisa-medlemmar/jimiwikman/
Categories don’t show any items, just the category itself: https://jimiwikman.se/fragearkiv/fragekategori/jira/
Am I doing the settings wrong or is there a conflict with my theme somehow?
