I have 0 unread articles. Then the next time I check newsblur (website) I have exactly the same set of unread articles again from several different blogs from early November:

Most of these are from Planet Debian, however there is one from github and one from Calvin and Hobbes.
I have seen articles from other feeds show up also, e.g. Dilbert. Not today however.
How do I make these articles stay read?
Other articles are OK, it only seems to be the above ones that are a problem.
