You do not have 2 default routes in your routing table. One is just pointing to a 10/8 which looks like an auto-summary of EIGRP (default on) and with ip default-network configured to 10.0.0.0. That way the route to 10/8 is also valid as 'default-network' not to be mistaken with 'default-gateway'. Sure you can get 2 default routes, but not through different protocols, you need to get 2 default routes advertised through the same protocol with the same cost/metric.
