Bounty's Value Won't Increase, But Gems Value Will?

Whenever someone kills another player their "Bounty" goes up by one. But instead of doing that, the bounty doesn't change?! The Gem value and Kill value change though..!? I'm not getting any errors or anything, do you guys know what the fix would be?

game.Players.PlayerAdded:Connect(function(plr)
	
	
	MC = plr:WaitForChild("MainCurrency")
	
	local Bounty = MC:FindFirstChild("Bounty")
	
	LS = plr:WaitForChild("leaderstats")
	
	local Deaths = LS:FindFirstChild("Deaths")
	
	local Kills = LS:FindFirstChild("Kills")
	
	plr.CharacterAdded:connect(function(char) -- Kill Mechs

	local humanoid
		
		repeat
			humanoid = char:FindFirstChild("Humanoid")
			wait()
		until humanoid
		
		humanoid.Died:connect(function()
			
			local tag = humanoid:FindFirstChild("creator")
			
			if tag and MC and LS then
				
				local killer = tag.Value
				
				if killer then
					
					Deaths.Value = Deaths.Value + 1
					
					local KMC = killer:FindFirstChild("MainCurrency")
					
					local Bounty = KMC:FindFirstChild("Bounty")
					
					if killer.MainCurrency.Bounty.Value < 100 then
						
						killer.MainCurrency.Bounty.Value = 			killer.MainCurrency.Bounty.Value + 1
					
						killer.leaderstats.Kills.Value = killer.leaderstats.Kills.Value
					
						Bounty.Value = Bounty.Value - Bounty.Value
						
						killer.MainCurrency.Gems.Value = killer.MainCurrency.Gems.Value + 1
					
					end
				end
			end
		end)
