It seems that pedestrian connects in asseet editor are affected by pedestrian path in another networks.
If I put a pedestrian connect near a station track, the height of pedestrian connect will be adjusted same height with station track. General road or avenue which has pedestrian path affects, too. If a pedestrian connect near the road, the height of pedestrian connect will be adjusted same height with the road. Even exported asset from asset editor, it can be modified in-game.
Is it possible that fix the height of pedestrian connects not to affected from another networks? I don't know why they made it like these ways.
