Why do players sort only in 2 teams when there are 4?

game.Players.PlayerAdded:Connect(function(player)
	
	local Teams = {
		game.Teams.Red,
		game.Teams.Blue,
		game.Teams.Yellow,
		game.Teams.Green,
	}

	for i,v in pairs(game.Players:GetPlayers()) do
		local prevPlayers, prevTeam

		for j,k in pairs(Teams) do
			if not prevPlayers then
				prevPlayers, prevTeam = #k:GetPlayers(),k 
			elseif prevPlayers <= #k:GetPlayers() then
				v.Team = prevTeam
			elseif prevPlayers > #k:GetPlayers() then
				v.Team = k
			end
		end
	end
	
end)

Players sort only in "Red" and "Green" teams instead of sorting in 4 teams. E.g if there are 4 players on team there will be only 2 on "Red" and 2 on "Green" instead of being 1 in each. Please help me.
