I was creating a menu and using the categories to do so. I had to make some changes in the wording of the categories. It seems that the software doesn't handle well the integrity of the categories. They show correctly in other parts of the blog but if I try to see them in the categories function they don't show up. I'm trying to rebuild it but the posts now show the categories duplicated. I remove the relationship to the post but I can't delete the duplicates.
