Civil Cell - Terrain Moving

Hello Team, 

Recently, we were brut forcing the modeling intersections in our project until we learned about Civil Cells. We have found them easy to edit and place, but we found that in some cases, the terrain moves and it causes some weird distortions in our model. In this case, the return on the North End of the following picture, the terrain moved. I added a point control to the Edge of Pavement of the return template so it could follow the proposed return line more closely, after it was done processing, the terrain just decided to move. The terrain did not move when I did the same process for the other return template. Is there a way to "anchor" the terrain so it doesn't move or distort? 

Please let me know if there's a way to solve this problem. I can provide more pictures and settings if possible!

Thank you for your time,
