Offline mode not working? v7.0

When I launch the iOS app (v7.0) while connected to the network, Newsblur happily syncs stories. I then open the site I want available when I’m offline and the stories are loaded. Now when I’m offline, I expect to have those stories available but the site list comes up blank. Am I doing something wrong? This happens immediately after loading the site, too (put into airplane mode).

App preferences are set to ‘Download stories’ and ‘Store 1,000 stories’.

I’ve also noticed if I back out of the site when I’m online and then immediately go back in, the initial list is blank again until it fetches the stories again. Is this normal?
