endless runner magnet waits for pick up

I built a magnet in BP but once he get active it “waits” to pick up coins before turn off.
i set the delay to 0.5 and 0.25 yet the coins still getting pull even after a 1.5 sec run with out coins.

build it from: Magnet - Blueprint Visual Scripting - Unreal Engine Forums
