ftf erases too much linework

[pacarter]

Our office is just getting started with Carlson.
We topo a vacant lot. I had to make some code corrections to the RW5 file. After processing the file with no adjustments, I used field to finish to redraw the linework that was corrected. Field to finish redrew the linework and erased some linework associated with points that were not corrected. What are we doing wrong?

Erase Existing Draw Field to Finish Entities: When checked, this option will erase from the drawing any old entities created by previous Field-To-Finish runs before drawing the new entities.
