Short description of error
Adding a blank material slot to a Grease Pencil object prevents the materials under it from showing in Change Active Material

Exact steps for others to reproduce the error

  1. Add a Suzanne GP object
  2. Add a blank materia slot
  3. Move the blank slot in the middle of the other materials
  4. Switch to drawing mode
  5. Press U key for the Change Active Material menu, and you'll see any materials that are underneath that blank slot will not show up in it.
