Terrain not showing correctly

[capitaldesigns]

I am working on plans for a new hillside house. I've imported a PDF of the grading plan I received from the civil engineer. I'm tracing over the existing contour lines using the elevation lines and assigning each line the elevation shown on the grading plan. When I view the plan in perspective view I see some very high peaks in the terrain. I don't know why this is happening. I've attached

the plan in a zip file. 

 

Does anyone know why this is happening and how I can fix it ?

Thanks,
Mike

check one of your elevation lines is 0.  See if that helps

Actually, two things.  Your lines are not connected AND the one side is at 0"   See vid

Thanks Michael. That was the problem. I did not catch that contour line was broken into 2 lines.
