Code based FPostProcessSettings variables are not displayed properly in the editor

When a variable of FPostProcessSettings is created, the variable itself is missing in editor with the actual post process settings fully expanded instead. Additionally, the fully expanded settings are not in the category the variable was assigned in code

Attached screenshot is what is seen in editor rather than the created variable.

Regression:
No - same behavior occurs in 4.16.3 (CL 3561208)

1. Open UE4 Editor (any project)
2. Add code based on Actor (MyActor)
3. Add the following include statement to MyActor.h above MyActor.generated.h:

   #include "Runtime/Engine/Classes/Engine/Scene.h"
   

4. Add the following to the class declaration:

   UPROPERTY(Category = "stuf", EditAnywhere, BlueprintReadWrite)
   	FPostProcessSettings RandomPostProcess;
   

5. Compile
6. Create blueprint based on MyActor (MyActorBP)

Result:
RandomPostProcess variable is missing from "Stuf" category and the post process settings are expanded out in the MyActorBP details panel

Expected:
RandomPostProcess variable is visible with post process settings displayed beneath it
