Cant display same array in two different blueprints


I’ve been following a very awesome tutorial on how to make inventory: UMG UI Inventory: Project Overview | 01 | v4.8 Tutorial Series | Unreal Engine - YouTube
Everything works fine in terms of functionality shown in tutorial but I fail to add an extra “chest” in the game. I.e. I tried to make a new chest actor which would hold few items. The chest HUD should show chest inventory and player inventory, so player cold swap items between these two arrays.

My issue is: the Chest HUD wont read values from player inventory - whenever I open chest, the Chest HUD shows empty player invnetory slots even if there are few picked up items.

Game HUD

Chest HUD - i just copied Game HUD (new array/item slots are not made yet, initially I tried to read currently owned items in order to proceed with another independent inventory which would bind items to the chest blueprint. I have no idea how to do it yet, so if someone could advise how to achieve it then I’d be grateful)

Pickup Dispacher:

Can someone please help me to make player inventory visible in Chest HUD? Let me know if you have to see any other important blueprints that are related with my issue.
Thank you in advance!
