Problem Bindable Event firing more than 1 time?

So I am making a voting system for my game, that two scripts communicate with each other: the main game script and the voting script. In the voting script I have some code to run when a bindable event, "Voting", fires. The problem is that the bindable event is firing multiple times and the global variables bug.

Look:

local AvMinigames = game.ServerStorage.Minigames.Images:GetChildren()
local display = script.Parent.Tela.SurfaceGui.Tela
local votesBEV = game.ReplicatedStorage.voting
local buttons = script.Parent:GetChildren()
local PlayerLocks = {}
local VotesWithMinigames = {}
local PlayerVotes = {}
local ButTouchedEVS = {}
local displays = {}

local function beVisible(bool)
	if bool == true then
		display.Visible = true	
		for i, v in pairs(buttons)do
			v.SurfaceGui.Nome.Visible = true
		end
	else
		display.Visible = false
		for i, v in pairs(buttons)do
			v.SurfaceGui.Nome.Visible = false
		end
	end
end

for i, v in pairs(display:GetChildren()) do
	if v.ClassName == "ImageLabel" then
		displays[#displays + 1] = v
	end
end

for i, v in pairs(buttons) do
	if v.ClassName ~= "Part" then
		table.remove(buttons, i)
	end
end

for i, v in pairs(buttons) do
	if v.Name == "Tela" then
		table.remove(buttons, i)
	end
end

game.Players.PlayerRemoving:Connect(function(player)
	if table.find(PlayerLocks, player) ~= nil then
		local minigame = PlayerVotes[player]

		VotesWithMinigames[minigame] = VotesWithMinigames[minigame] - 1

		display[minigame]:WaitForChild("Votos").Text = VotesWithMinigames[minigame]

		PlayerVotes[player] = nil
	end
end)

votesBEV.Event:Connect(function(caso)
	AvMinigames = game.ServerStorage.Minigames.Images:GetChildren()
	if caso == 1 then
		beVisible(true)
		local function checktouch(part, button)
			if part.Parent:FindFirstChild("Humanoid") then
				local character = part.Parent
				if table.find(PlayerLocks, character.Name) == nil then
					PlayerLocks[#PlayerLocks + 1] = character.Name
					
					local minigame = button.SurfaceGui.Nome.Text

					if VotesWithMinigames[minigame] == nil then

						PlayerVotes[character.Name] = minigame

						VotesWithMinigames[minigame] = 1

						display[minigame]:WaitForChild("Votos").Text = VotesWithMinigames[minigame]

					else
						PlayerVotes[character.Name] = minigame

						VotesWithMinigames[minigame] = VotesWithMinigames[minigame] + 1

						display[minigame]:WaitForChild("Votos").Text = VotesWithMinigames[minigame]
					end
				end
			end
		end


	for i, v in pairs(displays) do
		local imagenum = math.random(1, #AvMinigames)

		displays[i].Image = AvMinigames[imagenum].Image

		v.Name = AvMinigames[imagenum].Name

		script.Parent:FindFirstChild(i).SurfaceGui.Nome.Text = AvMinigames[imagenum].Name

		print("Image of minigame ".. AvMinigames[imagenum].Name.. " removed from the possibilities of minigames. ".. i)

		table.remove(AvMinigames, imagenum)

	end

	for i, v in pairs(buttons) do
		ButTouchedEVS[#ButTouchedEVS + 1] = v.Touched:Connect(function(touchedpart)
			checktouch(touchedpart, v)
		end)
	end
		
	elseif caso == 2 then
		beVisible(false)
		
		local MostVoted = {}
		local loop = 1
		
		VotesWithMinigames["Test"] = false

		for minigame, votes in pairs(VotesWithMinigames) do
			if minigame ~= "Test" then
				VotesWithMinigames["Test"] = true
				if loop == 1 then
					MostVoted = {minigame, votes}
				else
					if votes == MostVoted[2] then
						if not #MostVoted > 2 then
							MostVoted[3] = minigame

							MostVoted[4] = votes
							
						elseif #MostVoted == 4 then
							MostVoted[5] = minigame

							MostVoted[6] = votes
						end
					elseif votes > MostVoted[2] then
						table.clear(MostVoted)
	
						MostVoted = {minigame, votes}

						print("Minigame ".. minigame.. " with ".. votes.. " votes.")
					end
				end
			end

			for minigame, votes in pairs(VotesWithMinigames) do
				print(tostring(votes))
				if minigame == "Test"  and votes == false then
					local random = math.random(1,3)
						
					VotesWithMinigames["Test"] = nil

					MostVoted[1] = buttons[random].SurfaceGui.Nome.Text

					MostVoted[2] = 0

					print("Voting not done. Random minigame chosen: ".. MostVoted[1])
				end
			end

			if #MostVoted > 2 then
				if #MostVoted == 4 then
					local random = math.random(1,2)
					if random == 1 then
						table.remove(MostVoted, 3)

						table.remove(MostVoted, 4)

					else
						table.remove(MostVoted, 1)

						table.remove(MostVoted, 2)
	
					end
				elseif #MostVoted == 6 then
					local random = math.random(1,3)
					if random == 1 then
						table.remove(MostVoted, 3)

						table.remove(MostVoted, 4)

						table.remove(MostVoted, 5)

						table.remove(MostVoted, 6)

				elseif random == 2 then
					table.remove(MostVoted, 1)

					table.remove(MostVoted, 2)

					table.remove(MostVoted, 5)

					table.remove(MostVoted, 6)

				elseif random == 3 then
					table.remove(MostVoted, 1)

					table.remove(MostVoted, 2)

					table.remove(MostVoted, 3)

					table.remove(MostVoted, 4)

				end
			end
		end

			print("Most voted minigame: ".. MostVoted[1].. " with ".. MostVoted[2].. " votes.")
			_G.minigamec = game.Workspace.Minijogos[MostVoted[1]]

			VotesWithMinigames = {}
			PlayerLocks = {}
			PlayerVotes = {}
			
		for i, v in pairs(displays)do
			v.Name = i
			v.Votos.Text = 0  -- Reseta os nomes das imagens e o número (visível) de votos --
		end
		end
	end
end)

You don't need to understand the script, it's fine in itself, but the problem is what the output is indicating:

   14:56:58.258 false  -  Server  -  Voto:144   14:56:58.259 Voting not done. Random minigame chosen: Sinking tiles  -  Server  -  Voto:154   14:56:58.259 1  -  Server  -  Voto:144   14:56:58.260 Most voted minigame: Sinking tiles with 0 votes.  -  Server  -  Voto:205   14:56:58.260 true  -  Server  -  Voto:144   14:56:58.260 Most voted minigame: Furnace jumps with 1 votes.  -  Server  -  Voto:205   14:56:58.475 false  -  Server  -  Voto:144   14:56:58.476 Voting not done. Random minigame chosen: Furnace jumps  -  Server  -  Voto:154   14:56:58.476 Most voted minigame: Furnace jumps with 0 votes.  -  Server  -  Voto:205

You see? The output indicates that the piece of code is running 2 or 3 times and the minigame selection bugs.
