@yukinoh1989 Well whilst I haven’t checked your newer file here is where it was in your older file, where I detailed the issues. Both these faces are N-Gons.
This is because when we select one of the faces with vert select, we can see that there are nine verts connected to this one face.
Hope that clears things up.
