Default mesh problem with layers on symmetry plane and edges not aligned

Hello,

I use OpenFoam-2206, solver HiSA.

I want to perform 3D external supersonic simulations for symmetric geometry, I want to do it for 1/4 of the system (geometry and computational domain).

I set two patches as type "symmetryPlane;" but there were problem with layers on the end of computational domain - the layer disappears at the end of the computational domain. I changed patches from "symmetryPlane;" to "empty" and now layer is ok but I get this error with checkMesh:

Code:
Number of edges not aligned with or perpendicular to non-empty directions
Boundary in blockMesh file:

Code:
boundary
(
    
    sym1YZ
    {
        type empty; 
        faces
        (           
            (0 3 2 1) 
        );
    }
    
    
    sym2XZ
    {
        type empty;
        faces
        (           
            (0 1 5 4) 
        );
    }
Has someone any idea for solution with disappears layer or for above error?
