So it sounds like they were not removed from our publication by us -- if we had removed them from the publication, you wouldn't have even had the option available to remove them from the publication.

However, we have noticed problems with Medium not displaying publication information on our own articles -- that is to say, in the past several weeks, we have published some posts to our own publications where Medium wouldn't display them as appearing in the publication on the post itself-- even though I could see the post on the publication main page. It sounds like this is exactly what happened to you, also!

Unfortunately, it's outside of our control when this happens. We can't be sure when Medium will fix the problem, either, but I just want to be sure you know that we didn't remove your posts, and they're still available on our main site as well.
