One thing that might put dupes in the table could be VPN software but I am not sure... let me quickly test a theory....
Don't worry about that, it's not a problem with your config. It's just how your system is configured. For example, you could have one entry for 10.0.0.0/8 and another for 10.0.0.0/16, with different gateways. It would be potentially confusing, but not incorrect. But the inetmib1 code is buggy in this situation.
