Unable to edit instanced properties in the details panel

I’m working on making instanced pickups that can be added to a level and edited as needed. Everything I’ve seen online suggests that there shouldn’t be anything wrong with my setup, but I’m still unable to edit properties of the actual instance. Leading me to believe that the property actually isn’t being instanced at all.

I have 3 classes:
ReplicatedObject - with the following Macros

UCLASS(Abstract, Blueprintable, EditInlineNew, DefaultToInstanced)
class GAME_API UReplicatedObject : public UObject
{
	GENERATED_BODY()

public:
	UReplicatedObject();

...
}

Then I have an item class that’s inheriting from that

UCLASS(Abstract, Blueprintable, EditInlineNew, DefaultToInstanced)
class GAME_API UItem : public UReplicatedObject
{
	GENERATED_BODY()
public:
	UItem();

/** Various UPROPERTY() 's defining icon, static mesh, quantity, name and etc */
...
}

Lastly I have a pickup class, and this has a UPROPERTY of UItem that im trying to configure as an instance in the editor

UCLASS(ClassGroup = (Items), Blueprintable, Abstract)
class GAME_API APickup : public AActor
{
	GENERATED_BODY()
	
public:	
	APickup();

	UPROPERTY(EditAnywhere, BlueprintReadWrite, Instanced)
	UItem* ItemTemplate;
...
}

Inside the editor I made BP_PickupBase Blueprint class and set some default values, but as you can see I’m able drop down the item and edit its properties. But only in the base class

When I go to place the object in the level and configure it, I dont have any of the dropdown options. Just the ability to set ItemTemplate, as you can see here

If anyone has any suggestions or feedback, it would be greatly appreciated

Just figured out the issue.

It doesn’t appear that this was always the case, but any property that you want to be available in the details window of the instance must be set to EditAnywhere. All the properties that I was trying to edit were set to “EditDefaultsOnly” which wasn’t exposing it to the details window.
