Problem with while loop: overlapping visuals

https://gyazo.com/394ccb7e360cc414803219e160102c81

Here you can see the intended visual play normally at first
But when I click Priority again after clicking a different light sequence then it starts to overlap with the previous Priority sequence

Main, Server

function evaluateSeatAttrEnabled(seat:VehicleSeat, LightsContainer:Folder)
    if seat:GetAttribute('Enabled') == true then
        PatternBehaviors.modifyLightColor(LightsContainer, Color3.fromRGB(255, 255, 255))
    else
        PatternBehaviors.modifyLightColor(LightsContainer, Color3.fromRGB(0, 0, 0))
    end
    resetTransparency(LightsContainer, 0)
    cancelAllPartTweens(LightsContainer)
end

function evaluateCurrentSeatState(seat: VehicleSeat)
    local LightsContainer = seat.Parent:FindFirstChild('Lights')
    local lastPattern = seat:GetAttribute('CurrentPattern')

    -- Set the lights based on the seat's enabled state before checking the pattern
    evaluateSeatAttrEnabled(seat, LightsContainer)

    if seat:GetAttribute('Enabled') == true then
        while seat:GetAttribute('CurrentPattern') == lastPattern and seat:GetAttribute('Enabled') == true do
            local patternModule = require(LightPatterns[seat:GetAttribute('PatternType')]:FindFirstChild(seat:GetAttribute('CurrentPattern')))
            patternModule.activate(LightsContainer)
            task.wait()
        end
    else
        print('Disabled')
        -- Ensure that we reset the lights immediately when disabled
        evaluateSeatAttrEnabled(seat, LightsContainer) 
    end
  1. Here is my code in the Priority Module:
local PatternBehaviors = require(game:GetService('ReplicatedStorage').Modules.PatternBehaviors)

local module = {}

function module.activate(lightsContainer: Folder)
    local tweenTime = 2
    for i = 1, 5 do
        lightsContainer:FindFirstChild("L"..i).Transparency = 0
    end
    print('tweening priority')
    PatternBehaviors.modifyLightColor(lightsContainer, Color3.fromRGB(255,100,0))
    for _, part in (lightsContainer:GetChildren()) do
        if part:IsA('BasePart') then
            PatternBehaviors.Tween(part, {tweenTime}, {Color = Color3.fromRGB(255, 20, 0)})
        end
    end
    for i = 1, 5 do
        PatternBehaviors.Tween(lightsContainer:FindFirstChild("L"..i), {tweenTime}, {Transparency = 1})
    end
    task.wait(tweenTime)
end

return module

The setup looks like this:

Any ideas? on how to solve?
