Dialogue System

Open \Plugins\DialogueSystem\Source\DialogueSystem\Classes\BTDialogueTypes.h
And change

USTRUCT()
struct DIALOGUESYSTEM_API FBTDialogueCinematicOptions

to

USTRUCT(BlueprintType)
struct DIALOGUESYSTEM_API FBTDialogueCinematicOptions

In my case that is not the only one place which need to be fixed.
Also:
DialogueSystem\Source\DialogueSystem\Classes\Quest_Task.h
before

USTRUCT()
struct DIALOGUESYSTEM_API FQuest_Task

after

USTRUCT(BlueprintType)
struct DIALOGUESYSTEM_API FQuest_Task
