Line based building ghost aster editing the line path.

I created a Line based building, and I created the floor plans. Then later I modified the line of the line based building. Then I get a white duplicate of the same building before I edited the base line. Sims to be a ghost of the floor plans. Then after I closed the app and got back to the project, It seems to be gone the ghost. 

Any clue, why this thing happen?
