Issue with Benchmark case in GMSH
 

Hi,
I was trying out the 3D Benchmark related to STEP file input
https://gitlab.onelab.info/gmsh/gmsh.../step/wing.geo.
That worked fine but when I changed the input STP file to simple wing model and the box size needed for my wing, some issues have cropped-up. When I exported the mesh file in SU2 format the 'Markers' mentioned in the GEO file are not being written. I have attached the GEO file and a GOOGLE Drive link to the STP file (as I cant upload it here). I am unable to figure out the error and any suggestion would be greatly helpful.
Thanks in advance
