After paper2d character collides in his left/right/top side, it loses collision with ground

[GismoGK (iron berny)]

I’m a beginner at UE4; I’ve started exercising blueprint coding at paper2d, and, after setting up the walk, run and jump mechanics, the collision started to disappear after the character collides with any part that isn’t his feet.
Tell me if any more prints are needed

Here is the Jumping BP (The collision issue happened before the double jumping)

And the Falling + OnLanded BP
