TweenSize finishing faster than its desired time?

Hi there.

For some reason, when this runs, it completely skips the two seconds that the tween is supposed to be running for. it does it instantaneously. Any ideas?

mouse.Button1Down:Connect(function()
        animTrack:Play()
        stop = false
        while stop == false do
        wait()  
        for _,iore in ipairs(ore) do

            if cursorObject.Parent.Name == iore and magnitude <= 10 and hit == false and cursorObject.Parent.Health.Value > 0 then
                hitting = true
                hit = true
                local current = cursorObject.Parent.Name
                local currenthealth = replicatedstorge:WaitForChild("Health"):InvokeServer(current)

                local function executeAfter(complete)
                    print("hello")
                    replicatedstorge:WaitForChild("Mining"):FireServer(cursorObject,damage)
                    progress.Size = UDim2.new(0,0,1,0)
                    hit = false
                end

                local tween2 = progress:TweenSize(
                    UDim2.new(1,0,1,0),
                    Enum.EasingDirection.Out,
                    Enum.EasingStyle.Linear,
                    false,
                    2,
                    executeAfter
                )


            end
        end
    end 
end)
