Forum:Category Select Issue

On WhiteCollarWiki I have noticed that on some articles when I have added categories via Category Select and then saved the article, the categories 'disappear' from Category Select and 'appear' as regular text at the end of the article. When this happens the article does not appear in the any of the category pages. Here's a page with a good example of the issue: Out of the Box. This is an article where Category Select is working as it should: Pilot. Anyone have insights? --Ekrubmj 16:19, June 23, 2010 (UTC)
