I have a double listed Category listed in the Variables section of all my Blueprints, if I remove the last item of the Category the editor moves the top listed Variable into the Duplicate Category. Even if I remove or rename the Default Category it continues to list two of what ever the name is, so Components and Components are listed on top of each other with only item in the first listed Category.
I am wondering if you can reset the Categories to Default settings, or clean this up manually or if this is some sort of corruption in the Blueprint or is this a bug in the editor.
