It's not an error, just a warning!
Most probably, you have used in source the routed polyline with type, which isn't a standard type of roads for the MPC.
I repeat the questions:
1. Which tool you have used in the preparation of these SHP files for compilation by MPC?
2. Do you use the custom roads?
Most likely, the routing in your source is built incorrectly or it isn't accomplished ...
