This is expected. Tie switches have both FeederID and FeederID2 populated. The feature belongs to both feeders and has a parent section in each. WindMil models switches as a set of two partner switches. If you export one feeder or the other, but not both, Network Adapter still exports both partners. One of the two partners will be disconnected until you bring in the other feeder. After that, it will no longer be disconnected.
