I wonder how you created the surface that doesn’t mesh well. Try:
Explode > Rebuild Edges:

  1. Create a blend for the center profile using the edges of the middle surface.
  2. Split that blend curve using a point.
  3. Do a Sweep 1 across the edge of the middle surface and use the two curves from the split as sweep shapes.
  4. Mirror the resulting surface across the center plane.
  5. Match them a few times to create a smooth shape.
  6. Join them all together.

Somewhere in there, Rhino messed up.
