Quest System - Pick up Items

Hello there! I have an issue with my quest system… So, when i accept the mission from the NPC about picking some items, like a bush, when i pick these items the mission dont read the action and these items don’t go to my inventory! I can’t find the problem and this is a big issue do the project im doing.

So if someone could help me i would appreciate, sorry for something, im new in Unreal Engine!
