Full width "default" not working for "blogroll" page..

Hi!

I have a static landing page and therefore another page that lists my posts.

I want my posts full width, so I set the default for the theme pages and posts to “content” and the blogroll to “content sidebar”.

The latter setting overrides the setting for the posts and changes them from “content” to “content sidebar” too. How can I fix this? (The preview in the “change appearance” shows me the correct layout, but when I close it, it’s gone.)

Thanks in advance!
