REGRESSION: Yes, this does not occur in 4.21. This also occurred before CL 58120777, which fixed UE-47471

Duplicating or Copy/Pasting a component whose name ends in a number does not increment the name of the duplicate component correctly. It adds a "1" at the end instead of actually incrementing the number.

This occurs following the repro providing but there are inconsistencies with how the issue repro if you follow different steps (for example, if you do a chain of duped components, going back to a previous dupe and duping that, may result in correct name increments).

Steps to Reproduce


  1. Open QAGame in editor.
  2. Select the Floor mesh.
  3. In the Details panel, add a Scene component.
  4. Select the Scene component and duplicated it (Scene1 is created).
  5. Select Scene1 and duplicate it.


  1. Open QAGame in editor.
  2. Create and open an actor blueprint.
  3. Add a scene component (name defaults to "Scene")
  4. Duplicate the component (duplicate name is "Scene1").
  5. Duplicate Scene1.


Name of the new duplicate component is "Scene11".


The name should be "Scene2"
