Something wrong in "PowerUp"

I’m watching “PowerUp” View.
(9 - Communicating from C++ to Blueprints)

i have a problem.

in Video, the character’s PowerLevel slowly down.
but in my Unreal.
No Down.

always first value 2000 is same.

I think that there is no Value Down Code or Blueprint.

so, i surprised at video(down slowly PowerLevel Value)
What is i missed in Video.
