Some players not getting leaderstats points?

Hi, I did a script where a person clicks on a "Give all points" button, which makes it so everyone gets a menu popped up that makes them click on a confirm button to receive 25 points. However, some players are not getting those points.

Here are the scripts: Give all points button script:

script.Parent.MouseButton1Click:Connect(function()
	if game.ReplicatedStorage.PaidBlueMiles.Value == false then
    	game.ReplicatedStorage.AddPoints:FireServer(false)--u need to tell the server to do something, a client cant tell other clients anything, it have to go through the server
	elseif game.ReplicatedStorage.PaidBlueMiles.Value == true then
		print("Blue Miles are already paid")
		script.Parent.Text = "Blue Miles have already been paid!"
		wait(2)
		script.Parent.Text = "Pay out 25 Blue Miles"
	end
end)

Server script:

game.ReplicatedStorage.AddPoints.OnServerEvent:Connect(function(player,value)
    if value == false then
        game.ReplicatedStorage.AddPoints:FireAllClients()
        game.ReplicatedStorage.PaidBlueMiles.Value = true
    elseif value == true then
        player.leaderstats.Points.Value = player.leaderstats.Points.Value + 25    
    end
end)

Open menu script:

game.ReplicatedStorage.AddPoints.OnClientEvent:Connect(function()
    script.Parent:TweenPosition(UDim2.new(0,0,0.481,0))
end)

When you click on confirm script:

local secondMenu = script.Parent.Parent.Parent.SecondMenu
local firstMenu = script.Parent.Parent
local player = game.Players.LocalPlayer

script.Parent.MouseButton1Click:Connect(function()
    for i,v in pairs(firstMenu:GetChildren()) do
        v.Visible = false
    end
    secondMenu.Loading.Visible = true
    wait(2)
    secondMenu.Loading.Visible = false
    for i,v in pairs(secondMenu:GetChildren()) do
        if v.Name ~= "Loading" then
            v.Visible = true
        end
    end
    game.ReplicatedStorage.AddPoints:FireServer(true)
    wait(2)
    script.Parent.Parent.Parent:TweenPosition(UDim2.new(-0.4,0,0.481,0))
end)

I don't see what I'm doing wrong. Please help!
