Input disable and enable on own player-blueprint

Hello,
i have created a blank project with a simple player-blueprint for walking, looking and jumping (based on Teslas video: Unreal Engine 4 - Beginners Guide to Player Input (1/2) - YouTube). This is working so far.

However when I try to use “input disable” in my level-blueprint it’s not working. I still can run around. Am i missing something?
