Align Position Weird Replication Behavior

Hey everyone,

I have no idea what is going on with Align Position. I am not sure why replication behavior is different between the client and server. Any help or clarification would be greatly appreciated!

Clientside:

Code:
I am simply attaching the players pet model align position to the enemies attachment. Not sure why everything is fine on the client while on the server the pet floats even when the attachment is not floating. If I enable RigidityEnabled, replication is fine between the server and client. I wish to create tween effects and enabling Rigidity takes away from the smoothness.

function PlayerPetManager.StartAttack(player, target)
	pet.PrimaryPart:SetNetworkOwner(nil)
	local petBase = target.Parent.PetBase
	local attachment, pos = nil

	if not petBase.Position1:GetAttribute("Active") then
		attachment = petBase.Position1
		petBase.Position1:SetAttribute("Active", true)
		pos = petBase.Position1

	elseif not petBase.Position2:GetAttribute("Active") then
		attachment = petBase.Position2
		petBase.Position2:SetAttribute("Active", true)
		pos = petBase.Position2

	elseif not petBase.Position3:GetAttribute("Active") then
		attachment = petBase.Position3
		petBase.Position3:SetAttribute("Active", true)
		pos = petBase.Position3
	
	elseif not petBase.Position4:GetAttribute("Active") then
		attachment = petBase.Position4
		petBase.Position4:SetAttribute("Active", true)
		pos = petBase.Position4
	end

	if not attachment then
		print("no room to attack mob")
		return
	end

	pet.PetBase.AlignOrientation.Attachment1 = attachment
	pet.PetBase.AlignPosition.Attachment1 = attachment

	local trail       = replicatedStorage:WaitForChild("Misc"):WaitForChild("PetDirection"):Clone()
	trail.Parent      = pet.PetBase	
	trail.Attachment0 = pet.PetBase.Attachment	
	trail.Attachment1 = petBase.TargetAttachment

	-- Queue attack in coroutine
	PetStatus[player.Name] = true
	coroutine.wrap(function()
		wait(2) -- let pet arrive to mob
		--pet.PetBase.AlignPosition.RigidityEnabled = true
		while wait(2.5) do -- attack interval
                  -- attack sequence
		end
	end)()
end

All the best,
