Where is the mismatch? If it is the junction area, does the civil cell used (assuming a civil cell) have the same slope conditions as the main template? Does the main road have superelevation that could amend the hard shoulder slope, which in turn is not followed by the civil cell?
Do the templates match up? If there is a narrower shoulder (for example) in one of the templates, the slope to the existing ground will be closer to the road.
There are so many variations that could account for a mismatched side slope - all I would say is that if the templates are the same, there would / should not be any mismatch.
