How can I properly fix my ranking system?

I have tried making a ranking system based on a players stat but this does not work properly. When I test this in game I have 30k SP and should have the Master rank yet I still have the rank after that which requires 50k This is the code :

local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Modules = ReplicatedStorage:WaitForChild("Modules")
local Ranks = require(Modules:WaitForChild("Ranks"))
local CS = require(game:GetService("ServerScriptService"):WaitForChild("ChatServiceRunner"):WaitForChild("ChatService"))
local UpdateRank = function(Speaker, Player)
	local Leaderstats = Player:WaitForChild("leaderstats")
	local SP = Leaderstats:WaitForChild("SP")
	for key, value in pairs(Ranks) do
		local RequiredSP = value.RequiredSP
		local Color = value.Color
		local Name = key
		if SP.Value <= RequiredSP then
			local Character = Player.Character or Player.CharacterAppearanceLoaded:Wait()
			local Humanoid = Character:WaitForChild("Humanoid")
			local Head = Character:WaitForChild("Head")
			local Rank = Head:WaitForChild("Rank")
			local Label = Rank:WaitForChild("Label")
			Label.Text = Name
			Label.TextColor3 = Color
			Speaker:SetExtraData("Tags",{{TagText = Name, TagColor = Color}})
			break
		end
	end
end
CS.SpeakerAdded:Connect(function(Speaker)
	local Player
	Speaker = CS:GetSpeaker(Speaker)
	Player = Speaker:GetPlayer()
	if Player then
		local Leaderstats = Player:WaitForChild("leaderstats")
		local SP = Leaderstats:WaitForChild("SP")
		UpdateRank(Speaker, Player)
		SP:GetPropertyChangedSignal("Value"):Connect(function()
			UpdateRank(Speaker, Player)
		end)
		Player.CharacterAppearanceLoaded:Connect(function(Character)
			UpdateRank(Speaker, Player)
		end)
	end
end)

And here is the ranks module :

return {
	["Noob"] = {
		RequiredSP = 0,
		Color = Color3.fromRGB(231, 234, 18)
	},
	["Rookie"] = {
		RequiredSP = 100,
		Color = Color3.fromRGB(115, 115, 115)
	},
	["Average"] = {
		RequiredSP = 1000,
		Color = Color3.fromRGB(218, 0, 3)
	},
	["Expert"] = {
		RequiredSP = 5000,
		Color = Color3.fromRGB(10, 184, 236)
	},
	["Grinder"] = {
		RequiredSP = 10000,
		Color = Color3.fromRGB(18, 188, 72)
	},
	["Master"] = {
		RequiredSP = 25000,
		Color = Color3.fromRGB(68, 177, 136)
	},
	["Legend"] = {
		RequiredSP = 50000,
		Color = Color3.fromRGB(255, 255, 0)
	},
	["Heavy Grinder"] = {
		RequiredSP = 100000,
		Color = Color3.fromRGB(54, 54, 54)
	},
	["Unstoppable"] = {
		RequiredSP = 250000,
		Color = Color3.fromRGB(115, 0, 1)
	},
	["Hacker"] = {
		RequiredSP = 1000000,
		Color = Color3.fromRGB(0, 255, 0)
	},
	["Amazingly Good"] = {
		RequiredSP = 5000000,
		Color = Color3.fromRGB(158, 0, 197)
	},
	[":)"] = {
		RequiredSP = 10000000,
		Color = Color3.fromRGB(0, 0, 0)
	},
}

Thank you for taking your time to read this question.

You did a little mistake on line 13 (outside of module script)

local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Modules = ReplicatedStorage:WaitForChild("Modules")
local Ranks = require(Modules:WaitForChild("Ranks"))
local CS = require(game:GetService("ServerScriptService"):WaitForChild("ChatServiceRunner"):WaitForChild("ChatService"))
local UpdateRank = function(Speaker, Player)
    local Leaderstats = Player:WaitForChild("leaderstats")
    local SP = Leaderstats:WaitForChild("SP")
    for key, value in pairs(Ranks) do
        local RequiredSP = value.RequiredSP
        local Color = value.Color
        local Name = key
        if SP.Value >= RequiredSP then -- right here
            local Character = Player.Character or Player.CharacterAppearanceLoaded:Wait()
            local Humanoid = Character:WaitForChild("Humanoid")
            local Head = Character:WaitForChild("Head")
            local Rank = Head:WaitForChild("Rank")
            local Label = Rank:WaitForChild("Label")
            Label.Text = Name
            Label.TextColor3 = Color
            Speaker:SetExtraData("Tags",{{TagText = Name, TagColor = Color}})
            break
        end
    end
end
CS.SpeakerAdded:Connect(function(Speaker)
    local Player
    Speaker = CS:GetSpeaker(Speaker)
    Player = Speaker:GetPlayer()
    if Player then
        local Leaderstats = Player:WaitForChild("leaderstats")
        local SP = Leaderstats:WaitForChild("SP")
        UpdateRank(Speaker, Player)
        SP:GetPropertyChangedSignal("Value"):Connect(function()
            UpdateRank(Speaker, Player)
        end)
        Player.CharacterAppearanceLoaded:Connect(function(Character)
            UpdateRank(Speaker, Player)
        end)
    end
end)

You were checking if requiredSP is higher or equal to SP
