I've had a look through all the setting pages on my journal, but honestly I'm baffled. Is it just this entry that's being screened now or all of them?

The only thing I can think is (stupid question I know) whether you clicked the 'save' button right at the bottom of the page after you changed settings. I'm sure you did, though I didn't first time I tried to change settings, because I didn't see it. I'm dense like that! I'll keep thinking though. If it's just one entry, then maybe you can change things on the 'edit entry' option.

Otherwise, maybe threaten it? I just don't know...
