Value isn't resetting (but only sometimes, at random)?

[SpiralAPI (SFAST_Arlo)]

My game has a 1v1 duel arena. I have 2 “zones” for players to stand in and when 2 players stand in it then it teleports them into a fighting arena, and when time runs out or one dies it resets for the next 2 people.

For whatever reason though, it registers people as being in the zone forever when they are not.

I have tried everything I can to fix this. I am not too sure what to do about it now

Heres my code

local zone = require(game.ServerScriptService.ZoneHandle.Zone)

local p1 = zone.new(script.Parent.p1)
local p2 = zone.new(script.Parent.p2)
local fight = zone.new(script.Parent.FightZone)

local gIA = script.Parent.gameIsActive

local p1player = nil
local p2player = nil
local count = 0
local countdownOn = false

local rs1
local rs2

local function getLivePlrs()
	local plrs = fight:getPlayers()
	local newArray = {}
	for i, v in pairs(plrs) do
		if v.Character.Humanoid.Health > 0 then
			table.insert(newArray, v)
		end
	end
	return newArray
end

local function reset()
	print('resetted')
	local plrs = getLivePlrs()
	print(plrs)
	for i, v in pairs(plrs) do
		v.Character:SetPrimaryPartCFrame(CFrame.new(16, 10, -10))
	end
	p1player = nil
	p2player = nil
	countdownOn = false
	count = 0
	gIA.Value = false
	script.Parent.BoardPart.SurfaceGui.Count.Text = tostring("Waiting for Players")
end

local function startCountdown()
	print("countdownStarted")
	countdownOn = true
	count = 20
	coroutine.wrap(function()
		while wait(1) do
			if countdownOn == true then
				print(count, countdownOn)
				count -= 1
				print(count, countdownOn)
				script.Parent.BoardPart.SurfaceGui.Count.Text = tostring(count)
				local plrs = getLivePlrs()
				if count <= 0 or #plrs <= 1 then
					reset()
					break
				end
			elseif countdownOn == false then
				script.Parent.BoardPart.SurfaceGui.Count.Text = tostring("Waiting for Players")
				print(countdownOn)
				break
			end
		end
	end)()
end
