Why does the fence spin quickly at the first tap?

Question

unreal engine

I wrote this code to open the fence by clicking on the screen, but for some reason when you enter the game and click 1 time, it starts spinning and ends after a few seconds. I can’t attach a video here, so if you need a link to YouTube: https://youtu.be/is3SK9N2jNM
And yet, how to make it open smoothly?
