My root part size keeps changing from fat to skinny with the same stats, how do I fix this?

When this loads in the stats on the Humanoid, with the same numbers, sometimes I'm fat and sometimes I'm skinny. How do I fix this?

function addweight(h,s,n)
	local pf= stats:WaitForChild(n)
	h.BodyDepthScale.Value=s
	h.BodyWidthScale.Value=s
	h.BodyHeightScale.Value= pf.Height.Value
	pf.Size.Value= h.BodyDepthScale.Value
	
end

game.Players.PlayerAdded:Connect(function(plr)	
	local pf= nil
	if stats:FindFirstChild(plr.Name) == nil then
			 pf= script.plr:clone()
		pf.Parent=stats
		pf.Name= plr.Name
		end
	pf.StatsLoad.Value=false
	plr.CharacterAdded:connect(function(char)
		
		
		print("char")
		pf:WaitForChild("StatsLoad")
		pf.StatsLoad.Value=false
	
	wait()
	
	if stats:FindFirstChild(plr.Name) ~= nil then
		
		repeat wait() until continue
		continue=false
		print("stats load")
		if pf.Durability.Value < 100 then
			pf.Durability.Value = 100
		end
		if pf.Head.Value < 0.94999998807907104492 then
			pf.Head.Value= 0.94999998807907104492
		end
	plr.Character.Humanoid.WalkSpeed= pf.Speed.Value

		plr.Character.Humanoid.BodyHeightScale.Value= pf.Height.Value
		plr.Character.Humanoid.HeadScale.Value= pf.Head.Value
	
		plr.Character.Humanoid.BodyDepthScale.Value= pf.Size.Value
		
		
		plr.Character.Humanoid.BodyWidthScale.Value= pf.Size.Value
		
		pf.StatsLoad.Value=true
						
		addweight(plr.Character.Humanoid, pf.Size.Value, plr.Name)
		
		wait()
		
			
		plr.Character.Humanoid.MaxHealth= pf.Durability.Value
		plr.Character.Humanoid.Health= plr.Character.Humanoid.MaxHealth
		update:FireClient(plr, pf.Durability, pf.Strength)
		update2:InvokeClient(plr, pf.Durability.Value, pf.Strength.Value, pf.Height.Value, pf.Speed.Value)
		print("loaded all stats")
		
	
	end
	end)
