Image in a label doesn't reset on scripts request

hi, so I have used a community resource (Custom Inventory System: Full tutorial + Model - #11 by Fantasiuss) and made it a 6 slots limited inventory, however the problem comes when you would like to drop an item by dragging it out of the inventory. The item disappears however the icon stays.

Adding a print below the line thats supposed to reset the image prints on the output so the script does go thru the line but i guess there is something wrong with it
below is the part of the code that is the issue. I tried setting the .Image to “”; " "; 0; it just simply ignores the line of code which trys to change .Image of item slot. And as I spend already a decent amount of time on it I finally decided to ask for help.

local originalSlot = hotbar:FindFirstChild("SLOT" .. tostring(currentItemSelected.slotIn.Value))
			if originalSlot then
				originalSlot.itemImage.Image = ""
				originalSlot.UIStroke.Color = Color3.fromRGB(20, 20, 20) 
			end
			game.ReplicatedStorage:WaitForChild("Events").DropToolEvent:FireServer(currentItemSelected, currentItemSelected.Handle.Position)
