Meshing does not allow to define Named Selection on overlapping zones, so it seems to me that you do have two face zones. This is also highlighted by the fact that you have "wall-inner" and "wall-outer".

What method are you using for mesh interface creation? Is it one-to-one pairing? Use the following command to set it accordingly: define/mesh-interfaces/one-to-one-pairing? yes

Once you have set this method, you should be able to create the mesh interface.
