FFD_SURFACE_POINTS not created after SU2_DEF

[flybob91]

Dear SU2 developers,

I'm trying to set up a FFD box however, after having run the SU2_DEF command, I noticed that no FFD_SURFACE_POINTS are crated in the mesh_out.su2 file. I tried this successfully with SU2 v7 but repeating the same procedure with SU2 v5 lead to the problem. What can be the cause of such a problem? Is the procedure to create the FFD box the same between SU2 v7 and v5?

I tested the following .cfg file with the mesh mesh_NACA0012_inv.su2 and it's not working
