Gmshload3 only surface elements

We created a gmsh shape with cylinder_Gmsh_2D5.geo.
We output cylinder_Gmsh_2D5.msh in Gmsh format 2.2.
I am expecting a 3D cylinder (including the interior), but when I check the read labels in FreeFEM_gmshload3.edp, only 3 surfaces are read, but cannot see a Volume consisting of tetrahedra.
The volume consisting of tetrahedrons cannot be confirmed from Gmsh as shown in the attached image.

The attached is a geo file for gmsh.
