2D Image not appearing in game but only in scene

Hello. I am trying to fix an issue in which my Image is not appearing in my game view. I am making a 2D game and I wanted my enemy to have a health bar on top of them the entire time. The problem is that when I make the canvas "World Space" its almost as if the image vanishes in the game view and when playing. I checked if it disappears, in the scene, while playing but it doesn't. It is actually doing exactly what I want it to do in the regular game which follows the enemy and remain on top of it. Anyone have any ideas for how to fix this?
