The instance is getting pretty heavily loaded at the moment. Its possible something went wrong with saving the setting properly. Maybe in a few minutes try checking that the your settings are shown correctly in the UI and and then going to the front page again?
Hi. I know this is an old post but I was having the exact same issue. I just found that the solution that works for me is to refresh the entire page. Simply clicking the link to the homepage isn't enough; you must click the browser refresh button for it to work. Not sure why this is though.
Edit: Actually, it doesn't seem to work when changing the default Type for some reason. You can still give it a try if you haven't already. It works for me when changing the interface theme.
