My client regularly posts to his WordPress blog which I maintain. For awhile now, I've struggled to find out why WP is duplicating categories. For instance, if he posts to an existing category, WP creates a new category with the same name, but appends a unique number to the slug.
Can't figure out why. Can anyone help?
I have a screenshot of what it looks like in the dashboard here:
