Duplicate Category Not Deletable

[Strategon]

I created a duplicate category, but never used it. I cannot edit it or even delete it. Please fix.

If you can't edit or delete a Category, it's probably in use. You can see each Category's members by showing Categories in the Navigation Pane (Manage/Preferences, Navigation View), disabling Show Containing Object Hierarchy (in the Navigation Pane Options menu or F6), and scrolling down to the new Category.

If there aren't any members, and you're not accidentally trying to mess with a Global Category instead of your duplicate, you should report a bug at the Realm Works Bug Report site and keep a copy of your database for the devs to look at.
