I tried this in my save and I can duplicate the issue with this particular message
Do you have any other messages stuck ? It did go away for me if I deleted all the messages and it also seems to go away if I delete it and then close the notifiations and re-open.
Something is wonky though.
Moving this to bugs.
Definitely belongs in bugs. I have run into this issue in my save as well. Here is LE file I got. I tried deleting the notice followed by deleing all notifications. Deleting all notifications from the wall didn't seem to remove the notice but followed by closing the wall and reopening it, the notice didn't show. Something is definitely awry.
