I am having a similar problem to the one described here:
Eight categories appear in the drop-down at wp-admin/edit-tags.php?taxonomy=category and wp-admin/edit.php... but they do not appear in the actual list of categories. So, I can't delete them, which I would like to do.
Some of those categories appear down deeper in the hierachy, but I can't delete them at the root.
Is there something I need to do in order to remove them?
The blog I need help with is mainedoenews.net.
