Default Meshing a Periodic channel with high curvature 2D airfoil

I'm trying to mesh a 2D airfoil which represents a turbine blade by using this periodic channel that I saw in another thread. My mesh is shown in the attached picture.
I've made my own mesh that looks similar but when I turn it into an unstructured mesh I get a lot of errors saying periodic nodes do not have twins and I have a single edge problem around the perimeter of the mesh. Also attached is the picture of the problems I get when checking the mesh. Any help with why my mesh might have this error would help. Thanks.

It is normal in 2D. Dont worry about it and read the mesh in Fluent.

The grid isn't being accepted into fluent. When I try to read the mesh I get the error "Build Grid: Aborted due to critical error"

either make the mesh periodic in ICEM or change boundary condition (periodic) to wall or interface and then export mesh
