Comments

• Incident Diagnosis
  Wrong operator used on surface mesh.
  Here, "Remove edge" creates a quad which is split
  int the two previous triangles by tet filler.
  Thus, the interference is still here for the filler.
  Explanation : if we follow your scenario. We create
  a quad and not a triangle. This is a inconsistency in
  tetrahedron filler and you get an error.
  So, even is checker doesn't show any error in
  mesh, the filler stops.
  Correct Application
  Use "Swap edge" instead.
  This operator transforms two triangles in two other
  triangles which are not in interference.
