Help on Designing existing Terrain

I have designed the existing terrain and upon hitting the save button there are several data conflicts in my lines that come up in a window.  How do I find out which ones so I can make the changes.  It gives me a list but I am having difficulting finding out which ones they are.  Also I do not want to lose my work as I have spent over an defining the elevations with outlines, points, and countour line.  Please advise.  SEE ATTACHED SCREENSHOT.
