For Players In Pairs Only Doing One Player?

The script is breaking too early. I think it's because it is only adding one person to the table then stopping without adding others (or seeing if others can be added).

///ACTIVEPLAYERS TABLE BEING MADE

	while true do
		wait(5)
		ActivePlayers = {}
		for _, player in pairs(game.Players:GetPlayers()) do
			if player and player.Character then
				local humanoid = player.Character:WaitForChild("Humanoid")
				if humanoid and humanoid.Health > 0 then
					table.insert(ActivePlayers, player)
				end
			end
		end
		if #ActivePlayers > 1 then
			break
		else
			wait()
		end
	end

///PROBLEMATIC PART:

while MasterTime.Value > 0 do
		wait(5)
		MasterTime.Value = MasterTime.Value - 1
		
		ReallyActivePlayers = {}
		for _, player in pairs(ActivePlayers) do
			if player then
				local character = player.Character
				if character then
					local MatchTag = character.Torso:FindFirstChild("MatchTag")
					local Humanoid = character:FindFirstChild("Humanoid")
					if MatchTag and Humanoid and Humanoid.Health > 0 then
						table.insert(ReallyActivePlayers, player)
					end
				end
			end
		end
		if #ReallyActivePlayers <= 1 or MasterTime <= 0 then
			break
		end
end
