Prefabs cannot link to instanced GameObjects because they are not guaranteed to be there.

You will need to link it in the instanced prefab (after you add it to the scene) or assign it via script, likely in the Awake function.

It would be what you did in the first image, linking it in the scene.

HealthScript = targetObject.GetComponent(HealthBar1);

You would have to acquire the targetObject to do this.
