Unable to make power up respawn

This is my first time using unreal blueprints so I may just be missing something simple. I am working on a collectable power-up system for my game, similar to Mario kart pickups. I am able to make the box disappear on collision but I am unable to respawn it. Would anyone be able to see what is wrong? I have run breakpoints throughout and all of the functions call when they should do, but the boxes do not reappear.
