Lerping for cutscene is performing more than it is supposed to?

Hello!

So in my game there is a pretty basic cutscene where the camera basically glides cinematically around a scene. But in my code, the last few lines are supposed to have the camera set to a new location but stay still there. But when that happens is the lerping from before plays again... sorry if this is badly phrased, I can't find a better way. This is my code:

--// Client
local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Camera = workspace.CurrentCamera

--// Main
repeat wait()
    Camera.CameraType = Enum.CameraType.Scriptable
until Camera.CameraType == Enum.CameraType.Scriptable
Camera.CFrame = workspace.CameraPartCutscene.CFrame

wait(4)
wait(2)

Camera.CFrame = workspace.CameraPartCutscene2.CFrame

local to = workspace.to.CFrame 
local speed = 2 

game:GetService('RunService').Heartbeat:connect(function(step)  --http://wiki.roblox.com/index.php?title=API:Class/RunService/Heartbeat
    Camera.CFrame = Camera.CFrame:lerp(to,step/speed) --basic lerp
end)

wait(2)
Camera.CFrame = workspace.CameraPartCutscene3.CFrame

local to2 = workspace.to2.CFrame 
local speed2 = 2 

game:GetService('RunService').Heartbeat:connect(function(step2)  --http://wiki.roblox.com/index.php?title=API:Class/RunService/Heartbeat
    Camera.CFrame = Camera.CFrame:lerp(to2,step2/speed2) --basic lerp
end)
wait(5)
Camera.CFrame = workspace.CameraPartCutscene4.CFrame--Supposed to set the camera to a place and stay static, although it glides from camerapartcutscene4 to to2. weird
wait(2)
Camera.CFrame = workspace.CameraPartCutscene5.CFrame --Supposed to set the camera to a place and stay static, although it glides from camerapartcutscene5 to to2. weird

If you need a better idea understanding to my problem, here is a link to the game. Pay attention to the last shot. https://web.roblox.com/games/4572698580/anim

Sorry if my code is badly written or I'm not using it properly... I am new to lerp.

Thanks, any help is appreciated!
