Resetting Blueprint static mesh material switches it to WorldGridMaterial rather than the blueprint archetype

Steps to Reproduce
  1. Create a pawn BP
  2. Add a cube mesh to this BP
  3. Set the material of this cube to any non-default material + save
  4. Place the BP in the scene to create an instance, the cube with the material applied will appear.
  5. Select the instance and change the Cube material of that instance to any other material. Cube will update to the new material.
  6. With the instance still selected, go to the details panel Materials section, and select the curved arrow (the reset button)
  7. The cube material will revert to WorldGridMaterial instead of the default material set inside the BP.
