Pickup speed boost wont work.

Hello my friends.

I’ve been having trouble to get a speed boost pickup for my horror game to work. I don’t know if I did everything correct, but it seems like I’m not. What I’m trying to do is when I pick it up the AI’s speed will keep increasing. But whenever I pick up the sword hes speed never changes and is stuck at 0 which I set him to.
I need help to be done with it, if anybody helps thanks a lot.

Hey CoquiGames, thanks for the replay and here is a picture of the level blueprint.
