When selecting a component in a blueprint, any categories that also have subcategories will appear in the details panel along with the component’s details. This was occurring in my own project and I was able to reproduce it in a new Third person project (though an empty one should also work).
Reproduction Steps
- Create a new Third person template project in 4.12 (optional).
- Open the ThirdPersonCharacter Blueprint (or create a new one and add any component to it).
- Add a new variable and set it’s category to any subcategory (ie: “MyCategory|SubCat”).
- Compile the blueprint.
- Ensure you have the details panel open (Window → Details Panel).
- Click on the CharacterMovement component (or any component) and look at the details panel. Among the properties of the component you will see the variable you just made.

Note: the “CustomCodeCategory” was added in the BP’s base class to test if it happened from code too.
