One way collision on COllisionPolygon2D not activated

I have a complex CollisionPolygon2D node as my terrain in a 2D side-scroller game. I want it to be one way collision so my player can jump up through the bottom and sides of the polygon, but it seems that my player can not enter the shape from the bottom at all. If anybody has any experience with CollisionPolygon2Ds and one way collision please help, thank you!

(Also, I’m not sure if it is due to my engine version, I will take a look at that later)
