Why is my raycasting being weird when I try to ignore certain parts?

I am attempting to make a laser gun and everything is working fine until I aim my gun at a SpawnLocation and then instead of the beam ignoring it and going through it the beam just goes to an entirely different position as if it is trying to avoid the spawn locations even though I am using the ignore list. I get no errors in the output. what do you guys think?

DetectRayHit.OnServerEvent:Connect(function(player, ray, startPos, orientation, BulletSpeed, Damage)						
																						
		local part,position = workspace:FindPartOnRayWithIgnoreList(ray, {player.Character,workspace:WaitForChild("SpawnLocation")})
		
		if part ~= nil then
			
			local beam = game:GetService("ReplicatedStorage"):WaitForChild("Lasers").TX08Bullet:Clone()
			beam.Parent = workspace
			beam.Position = startPos
			beam.Orientation = orientation

			local tweenInfo = TweenInfo.new((beam.Position - position).Magnitude * 1 / BulletSpeed, Enum.EasingStyle.Linear, Enum.EasingDirection.In, 0,false,0)
			
			local Tween = TweenService:Create(beam,tweenInfo,{Position = position})
			
			Tween:Play()
				
			beam.Touched:Connect(function(hit)
				if hit ~= nil then
					local Humanoid = hit.Parent:FindFirstChild("Humanoid")
					if hit.Parent:FindFirstChild("Enemy") then
						Humanoid:TakeDamage(Damage)
						if Humanoid.Health == 0 then
							for i,v in pairs(hit.Parent:GetChildren()) do
								DS:AddItem(v,.5)
							end
						end
					end
				end
			end)
				
			Tween.Completed:Connect(function()
				if beam ~= nil then
					DS:AddItem(beam,.2)
				end
			end)
			
		end
		
end)
