I get "blueprint runtime error" when I stop "move component to" from another event

Before I had a simple “move component to”

to move coins from right part of the screen to the left, but i added magnet to the game and wanted to make them move to the player. I added collision and some nodes from tutorial and made them move to the player, but they would act really strange, I realised that its becouse they were already ordeder to me to anothor place, so i added sequance to stop them if magnet effect is happening, and now it works as I want, but I get this errors. What should I do?

I fell like I need to call stop from the event as movement, but I have no idea how
