Details panel missing for static mesh component in blueprint

Sorry for delay in getting back to you. I have still been unable to see same behavior you showed. This is how it looks for me:

This is what I have been doing:

  1. Create a new project using First Person template.
  2. Add a new code class derived from Pawn.
  3. Add code you provided to create Capsule, Static Mesh, and Camera components.
  4. Create a Blueprint from custom class I just created.
  5. Open Blueprint and go to Components tab.

Are you making any alterations to class at any point?
