Player's team changes once, doesn't change again?

Hi, i'm making a Juggernaut Game with my friend, and the game works, once. All of the players team get changed to sheriff and juggernaut, and the game goes on normally, but then the second round starts, when only the juggernaut gets changed, but the sheriffs don't. Is there any to fix it?

local maps = game.ReplicatedStorage:WaitForChild("Maps")
local juggernaut = nil
local players = game.Players:GetPlayers()
local revolver = game.ReplicatedStorage.Revolver
local knife = game.ReplicatedStorage.Knife
local allplayers = {}
local gamestarted = false
local juggernautplrs = game.ReplicatedStorage.Values.JuggernautPlayers
local sheriffplrs = game.ReplicatedStorage.Values.SheriffPlayers
local spawnspawns = game.Workspace.Spawn.Spawns:GetChildren()
local gameending = false
game.Players.PlayerAdded:Connect(function(plr)
    game.ReplicatedStorage.Values.plrs.Value = game.ReplicatedStorage.Values.plrs.Value+1
    table.insert(allplayers,plr)
end)
game.Players.PlayerRemoving:Connect(function(plr)
    game.ReplicatedStorage.Values.plrs.Value = game.ReplicatedStorage.Values.plrs.Value-1
        table.remove(allplayers,FindIndex(allplayers,plr))
end)
function FindIndex(Table,Val)
    for index,v in pairs(Table) do
        if v == Val then
            return index
        end
    end
end
function loadmap()
    local maplist = maps:GetChildren()
    local map = maplist[math.random(1,#maplist)]
    local nmap = map:Clone()
    local name = nmap.Name
    nmap.Parent = workspace
    nmap.Name = "Map"
    game.ReplicatedStorage.Values.Status.Value = "Chosen Map: "..name
end
function unloadmap()
    if workspace:FindFirstChild("Map") then
        workspace.Map:Destroy()
    end
end
