Admin Panel Ban script failing to ban players? Please help!

Hello fellow scripters.

I am currently making an admin panel for my game, and so far I have kick, kill, broadcast and shutdown events working. I also have a ban event but that does not seem to be working? This is the reason I am here.

I have a GUI, well, It's better to show you.

Here is the ban script:

function script.Parent.OnServerInvoke(player, Data)
	
	local Target = Data[1]
	local Reason = Data[2]
	
	local Player = game.Players:FindFirstChild(Target)
	
	local HasPlayer = not Player == nil

	local HasReason = not string.len(Reason) == 0	
	
	local DataStore = game:GetService("DataStoreService"):GetDataStore("motfAdminPanel")
	
	local ID = nil	
	
	if HasPlayer then
		
		ID = Player.UserId
		
		for _,v in next, _G.immuneToBan do
			if v == ID then
				return "exempt"
			end
		end
		
		if HasReason then
			Player:Kick("You have been banned.");
		else
			Player:Kick("You have been banned for the following reason: " .. Reason)
		end	
	end
	
	if ID == nil then
		local success = pcall(function() ID = game.Players:GetUserIdFromNameAsync(Target) end)
		
		if not success then
			return "noplayer"
		end
	end
	
	for _,v in next, _G.immuneToBan do
		if v == ID then
			return "exempt"
		end
	end
	
	if ID < 0 then
		return "guest"
	end	
	
	if HasReason then
		DataStore:SetAsync(ID, Reason)
	else
		DataStore:SetAsync(ID, 1);
	end
	
	return "banned"
	
end

And if it's required, here is the kick script:

function script.Parent.OnServerInvoke(player, Data)
	
	local Target = Data[1]
	local Reason = Data[2]
	
	local Player = game.Players:FindFirstChild(Target)

	if Player == nil then
		return false
	end
	
	if string.len(Reason) == 0 then
		Player:Kick("You have been kicked.");
	else
		Player:Kick("You have been kicked for the following reason: " .. Reason)
	end
	
	return true
end

These are all in events, as shown in this picture: https://imgur.com/GFudgvE

I would really appreciate help. Thanks, guys!
