Curved lines appearing on mesh with snappyHexMesh

Greetings!
I have been trying to get rid of the curved lines shown on the picture. The version of OpenFOAM used is 3.0.x. I used a .stl file, then ran snappyHexMesh with only the castellatedMesh control set to true. The mesh was good, so I went to the next step, which was setting the snap control switch set to true. However, after the snappyHexMesh finished the run, I noticed some curved lines on the mesh. I searched information about this but I just couldn't find any. Perhaps I'm using the wrong words, since I'm new to CFD and english is not my native language. Any help is appreciated! Thanks in advance!
Code:
snapControls
{
//- Number of patch smoothing iterations before finding correspondence
// to surface
nSmoothPatch 3;
//- Relative distance for points to be attracted by surface feature point
// or edge. True distance is this factor times local
// maximum edge length.
tolerance 1.0;
//- Number of mesh displacement relaxation iterations.
nSolveIter 300;
//- Maximum number of snapping relaxation iterations. Should stop
// before upon reaching a correct mesh.
nRelaxIter 5;
// Feature snapping
//- Number of feature edge snapping iterations.
// Leave out altogether to disable.
nFeatureSnapIter 10;
//- Detect (geometric) features by sampling the surface
implicitFeatureSnap true;
//- Use castellatedMeshControls::features
explicitFeatureSnap true;
//- Detect features between multiple surfaces
// (only for explicitFeatureSnap, default = false)
multiRegionFeatureSnap true;
}
Kind regards
