Widget Editor Utility don't expand properties

[Matdelarue]

Hello guys, I was trying to implement a Widget Editor Utility (WEU), to make it easier to create my action system.

My action system consists of an array of actions, each action is defined like this:

UCLASS(Blueprintable, DefaultToInstanced, EditInlineNew, BlueprintType)
class POKEMONGAME_API UCutsceneAction : public UObject, public FTickableGameObject
{
     ...
};

So I have different subclasses with different variables, and everything works well in the editor. I can modify the variables inside each class when they’re inside the array.

But for some reason, when I show this in the WEU, I don’t have the option of expanding it to see what’s inside.

So for the moment, I didn’t find any answer so I’m hoping somebody knows what to do. I’m working on blueprints and this is my code for the WEU.

Thanks for the help!
