NIOS II Editor Driver Name

As an update to try to debug this issue I built a new simple_socket_server app and bsp on the older PC (NIOS II 13.0sp1 SBT), and the exact same example (using the templates both times) on the new PC (NIOS II 13.1 SBT), and used the same .sopcinfo file for both builds. The old PC has the TSE MAC Driver Name correct (along with the check box), the newer PC has the TSE MAC Driver Name empty and no check box. I guess I am confused on how two supposedly identical builds with same .sopcinfo file have different results. Are there other settings that need to be modified to get the Driver Name correct?
