Collision not consistently firing BP

Hi all, I created a harvestable blueprint called Weed_Blueprint, the idea is when the player overlaps the collision box and hits “F” it will change the color and generate a pickup, however sometimes the weed does not change color and the BP does not fire. I am not sure what the issue is. Here is the weeds graph: Collision > | PasteBin For Unreal Engine 4 and images are attached of what happens at run time.
