Unable to update Route Resource Data Entity

We are trying to upload new route data for existing and new released products but keep getting a error message stating that the routeid record is duplicate. Does anyone know if the sequence of data entities has changed or if MSFT has modified the way a import record is assigned a new record it?

See error when attempting to load data entity Route Resources
