Collision generates overlap event without a Character triggering it

When using OverlapAll as a collision preset on a Cube, the collision will trigger when placed near a wall even if the Character has not collided with the Cube.

1. Create a project with ThirdPerson Template
2. Create a Blueprint with a basic Cube, and set Collision Preset to "OverlapAll"
3. Create Event "ActorBeginOverlap" and print string "Overlap"
4. Create Default New Level and add a wall
5. Add the Blueprint near to the wall and higher than the capsule of the Character
6. Play the level, and touch the wall under the Cube

Results: The Cube generate overlaps when I touch the wall.

Expected: The Cube just generate overlaps when the player pass through it
