Weird bug script picking up previously clicked items

[Lokispades]

Weird bug started happening when I added the Billboardgui system to my game, the previous clicked placements that support billboardgui get picked up when not ordered to. Video is provided for a better explanation.

Video:

Code:

Mouse.Button1Down:Connect(function()
	if not Placement_Hologram and Mouse.Target ~= nil then -- if not placing hologram and mouse target is not nil to avoid error
		
		local Clicked_Target = Mouse.Target
		local Target_Ancestor = Mouse.Target:FindFirstAncestorOfClass("Model")
		
		-- if clicked target does not have clickdetector and Target_Ancestor is found and has Tag EditablePlacement
		if not Clicked_Target:FindFirstChildOfClass("ClickDetector") and Target_Ancestor and Target_Ancestor:HasTag("EditablePlacement") then
			
			if PlayerIn_EditMode then -- If in edit mode and not placing any placements

				QuickGuide.Adornee = Clicked_Target
				QuickGuide.Enabled = true
				
				QuickGuide.Content.Pickup.MouseButton1Click:Connect(function()
					if not DB_2 then DB_2 = true
						local Result, ErrorMsg = pcall(function()
							PickUpPlacement:FireServer(Target_Ancestor) -- sends mouse target ancestor to "Placement"
						end)

						if not Result then
							warn("Failed To Pick Up", Mouse.Target.Name, "ErrorMsg:", ErrorMsg)
						end
						
						DB_2 = false
					end
				end)
				
				-- ADD delete HERE

			else
				print("Player Edit Mode Is:", PlayerIn_EditMode)
			end

		else -- if clicked placement or object has no tag
			QuickGuide.Enabled = false -- turns off QuickGuide aka "Pickup & Delete" when player press something that is not a placement
			return -- print("No Tag")
		end

	end
	
	
end)

May i see the PickUpPlacement:FireServer(Target_Ancestor) script?

1. You may be clicking twice, maybe add a cooldown.
2. Could the Target_Ancestor also contain the other item as well?
3. Add a print statement right above the PickUpPlacement:FireServer(Target_Ancestor), to see what the Target_Ancestor is.

I added the print statment and it seems like the event function runs more than once

PickUpPlacement:

function CallerFor_SaveLoad_Placement(Player:Player, Save:boolean, Placement, cframe)
	if not DB then DB = true
		
		if Save then -- if save placement		--Tip: "SaveLoad_Tools" is called before saving placement to prevent duplications of placements
			local Found_Placement = Placable_Objects:FindFirstChild(Placement):Clone()
			--
			Manager.SaveLoad_Tools(nil, Placement, nil, true) -- Remove Placement Tool Table
			--
			Manager.SaveLoad_Placement(nil, Placement, cframe) -- Save Placement To Table First
			--
			Found_Placement:SetPrimaryPartCFrame(CFrame.new(cframe.Position.X, cframe.Position.Y, cframe.Position.Z) *  CFrame.Angles(cframe:ToEulerAnglesXYZ())) -- Sets Position and orientation before parenting to "Placed_Objects"
			Found_Placement.Parent = Placed_Objects -- Clones "Found_Placement" and parents it to "Placed_Objects"
			
		else -- if not save then remove
			local Found_Tool = PlacementTool:FindFirstChild(Placement.Name) -- Finds Placement Toole
			--
			Manager.SaveLoad_Placement(nil, Placement.Name, nil, true) -- Removes Placement Table
			Placement:Destroy() -- Destroyes The Clicked Placement
			--
			Manager.SaveLoad_Tools(nil, Found_Tool.Name, nil, nil, true) -- Adds Placement Tool To Table
			Found_Tool:Clone().Parent = Player:FindFirstChild("Backpack") -- Clones Placement Tool To Backpack
		end
		
		DB = false
	end
end

PlacePlacement.OnServerEvent:Connect(function(Player, PlacementName, cframe)
	CallerFor_SaveLoad_Placement(Player, true, PlacementName, cframe)
end)

PickUpPlacement.OnServerEvent:Connect(function(Player, Placement)
	--print(Placement)
	CallerFor_SaveLoad_Placement(Player, false, Placement)
end)

You can see here Target_Ancestor is getting printed more than once
