How do I get Directional Light on Occlusion Mapped Tiles to cast a shadow on my player?

Hey I'm new to 2D Lighting in Godot and I just followed a video where I could map the areas where a showdow would be marked by marking an occlusion layer in the tile set and it seems to be working but it doesn't seem to be affecting my player or the background.

I thought it was an ordering issue but that seems to not be the case.

the player is the small Mushroom guy btw
