Solved - Can't set variables in the editor from my C++ class

(Solved is at the bottom of this post)

My C++ is like this…

#include "GameFramework/Actor.h"
#include "ContentChunk.generated.h"

/**
 * 
 */
UCLASS()
class TDL2_API AContentChunk : public AActor
{
	GENERATED_BODY()
	
public:
	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = ContentChunk)
	int16 xIdx;
	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = ContentChunk)
	int16 yIdx;
};

And in the editor I have made a blueprint. Then dragged the blueprint to the level twice so I have 2 of them. It looks great, but… the xIdx and yIdx are greyed out so I can’t edit them.

I searched quite a bit and tried many changes to the UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = ContentChunk) lines to no avail. There is one older posting that suggests a fix, but the flag is deprecated.

SOLVED - Turns out the int16 does not work. I tried float and it worked, then UINT16 did not work. Then int32 which does work.
