Double upload traffic across Speedfusion L2

We have noticed issues on our network since implementing the speedfusion L2 vpn to an office 5 minutes up the road from HQ. We can duplicate the problem easily. It appears all traffic coming from HQ out to the internet will also traverse the L2 VPN, essentially doubling our packets, congesting the network and I think halving our upload bandwidth. Its causing lots of intermittent issues on the network. Any ideas out there?
