Script Shows GUI on the first Chest, but then doesnt show gui on any other chests, why?

My Problem is that when i spawn in, it spawns the chests, then I go up to the first one and it shows the gui. But when I walk Up To The Second Chest it does not show the gui for some reason but i can go back to the first chest and it will show the gui again.

Script:

local Chests = workspace.Chests
local Range = 10
local P = game.Players.LocalPlayer
local C = P.Character or P.CharacterAdded:Wait()
local Hb = game:GetService("RunService").Heartbeat

function Check()
    for i,v in pairs(Chests:GetChildren()) do
        if (v.Hitbox.Position - C.PrimaryPart.Position).Magnitude <= Range and not v.Openers:FindFirstChild(P.Name) then
            local Pos = workspace.CurrentCamera:WorldToScreenPoint(v.Hitbox.Position)
            script.Parent.Open.Position = UDim2.new(0,Pos.X,0,Pos.Y,0)
            script.Parent.Open.Visible = true
        else
            if script.Parent.Open.Visible then
                script.Parent.Open.Visible = false
            end
        end
    end
end
