S&S Profile Display, Pipe Cover, and Delete Ink lock

MicroStation V8i (Selectseries 2) - Version 08.11.07.443

Bentley InRoads V8i (Select Series 2) - V08.11.07.615

1. When I display/create my drainage structures on my existing profile, whether or not delete ink is on or off or if I have pencil on or off, it will not delete the old graphics, it just puts it right on top of what's displayed already.

2.Also I have a pipe connected between two inlets side by side and it will not display properly.

3.And my last issue is with pipe cover. When I displayed my drainage, it would not display properly unless I chose to start at a smaller station and went up even though that is going from downstream up. However when I go to display my pipe cover, it says that my flow contains direction errors.
