One cell's terrain is WAY below all the rest. How do I raise the terrain to the same level as the rest?

As you can see the ground in this cell is WAY below the water level and the rest of the terrain level of the rest of the worldspace. How in the heck do you lift an entire cells terrain height. I even tried the landscape tool and I maxed out the height the tool would do and it was STILL way below the water level. The second image is the edge of the cell. You can see there is no other terrain next door. The third image is if I raise the camera straight up from the 2nd image. You can see the other cells are at the proper terrain height.

Got it fixed. For anyone else - open Xedit and then find a good cell in Worldspace (NOT CELL) - then find the Landscape record. Find your bad cells - compare good landscape and bad landscape. Copy the Vertex Normals and Vertex Height Map from good to bad.
