snappyHexMesh Skewness error

I'm trying to successfully mesh a complex geometry including some nozzles with snappyHexMesh. Although everything seems to work smoothly and all boundaries out of the .stl files get added, one error always remains that is:
***Max skewness = 5.30808, 5 highly skew faces detected which may impair the quality of the results
<<Writing 5 skew faces to set skewFaces
Although I tried to play around with some parameters in the snappyHexMeshDict, it won't get better. For example increasing the max refinement level from 4 to 5 will even increase the number of highly skew faces from 5 to 7. Using "refineWallLayer" did not help either. So is there any possibility to avoid highly skewed (sur)faces? By the way, the snappyHexMeshDict file is attached.
The .stl file was a 2D Triangular Mesh from Salome, if that info is useful.
Since other posts did not help, any help would be appreciated.

This Error is not crucial. You can start and run the calculation with this minor problem.
It is also possible to view these skewed faces in paraview via include sets.
