How do I delete previous game.Players:GetNameFromUserIdAsync(tonumber(data.key)) data?

I've been getting the error message Players:GetNameFromUserId() failed because HTTP 404 (NotFound) because I tried testing my leaderboard in a local server and I'm wondering how I can delete previous data that's been stored. The reason why it broke is because the user id of a player from a local server is a negative number. For example, Player1 would be -1. I can fix this if I can delete the data but I'm not sure how. If there is anything else that you think might fix this please let me know.

Here is the script I'm using:

 local DataStoreService = game:GetService("DataStoreService")
local WinsLeaderboard = DataStoreService:GetOrderedDataStore("WinsLeaderboard")

local function updateLeaderboard()
        local success, errorMessage = pcall (function()
                local Data = WinsLeaderboard:GetSortedAsync(false, 5)
                local WinsPage = Data:GetCurrentPage()
                for Rank, data in ipairs(WinsPage) do
			    local userName = game.Players:GetNameFromUserIdAsync(tonumber(data.key))
			           local Name = userName
                       local Wins = data.value
			           local isOnLeaderboard = false
                       for i, v in pairs(game.Workspace.GlobalLeaderboard.LeaderboardGUI.Holder:GetChildren()) do
                             if v.Player.Text == Name then
                                  isOnLeaderboard = true
                                  break
                           end
                    end

                     if Wins and isOnLeaderboard == false then
                            local newLbFrame = game.ReplicatedStorage:WaitForChild("LeaderboardFrame"):Clone()
                            newLbFrame.Player.Text = Name
                            newLbFrame.Wins.Text = Wins 
                            newLbFrame.Rank.Text = "#"..Rank
                            newLbFrame.Position = UDim2.new(0, 0, newLbFrame.Position.Y.Scale + (.08 * #game.Workspace.GlobalLeaderboard.LeaderboardGUI.Holder:GetChildren()), 0)
                            newLbFrame.Parent = game.Workspace.GlobalLeaderboard.LeaderboardGUI.Holder
                     end
              end
      end)

      if not success then
            print(errorMessage)
      end
end

while true do

        for _, player in pairs(game.Players:GetPlayers()) do
              WinsLeaderboard:SetAsync(player.UserId, player.leaderstats.Wins.Value)
        end

        for _, frame in pairs (game.Workspace.GlobalLeaderboard.LeaderboardGUI.Holder:GetChildren()) do
              frame:Destroy()
        end

        updateLeaderboard()
        print("Updated!")

        wait(10)
end
