The surface for the entry turn "T", There appears to be a defect in the surface/profile at the intersection of the main road and the side road.
This may caused by the reference element most likely using an extend to intersection.
To fix this select the cell CL (Red line) open the properties / element information. > Under the Transition offset Rule, change the value from Base Geometry to Extended.
this allows the offset element (CL) to follow the reference element (Gap). the gap was introduced when the element was extended to the intersection.
Alternately it may also be that the profile was inadvertantly shortened, in this case the shortest common denominator (Hz or Vt) is used in the terrain. Feel free to send me the file for varification

BTW... this really isnt a "fix" as the element is only reacting as it is supposed to. hopefully as we move forward this type of behavior will become common knowledge...
